Value of Rare Australian 50 Cent Coins

Australian 1977 Silver Jubilee 50 cent

Australian 1977 Silver Jubilee 50 cent

One of the most popular Australian coins to collect is the 50 cent coin. And one of the most popular question about Australian coin values that we get is of course, about what is the value of Australian 50 cent coins that can be found in your change. That’s because the 50 cent coin is big, it has been issued with many different commemorative designs since it’s release in 1966 and the large size of the coin means the designs really stick out when you receive them in change. Sometimes you’ll get a 50 cent in your change and you’ll turn it over and Captain Cook will stare back at you and you’ll either have never seen one before or not have seen one for years and you’ll think….how much is that worth? It must be worth something right? It was minted 38 years ago and you almost never see them any more! Surely an old Australian 50 cent coin is worth some money? After all, some of them are more than 40 years old now!

Well a lot of the time that fifty cent you don’t remember seeing before is usually worth…wait for…50 cents. Yes, 50c. Sad but true. See the thing is, a lot of these commemorative coins were minted, and when I say a lot I mean a lot. After all, they were intended to circulate so the Royal Australian Mint churned them out in their millions and tens of millions. The other problem is that the public at the time hoarded these things so there are tens of thousands of money boxes loaded down with uncirculated or near uncirculated examples of them. So sadly most Australian 50 cent coins are anything but rare. It’s worth having a look at the mintages of the commemorative 50 cent coins up until 2000 and the catalogue values of an uncirculated example (there have been a spate of them since then, and I don’t think it’s worth covering them). The mintages and CV’s are from the 2009 Pocket Guide to Australian Coin and Banknotes.

  • 1970 Captain Cook Bicentenary 50 cent, mintage: 16,548,100, $7.00
  • 1977 Silver Jubilee 50 cent, mintage: 25,067,000, $4.00
  • 1981 Royal Wedding 50 cent (Charles and Diana), mintage: 20,000,000, $6.00
  • 1982 Commonwealth Games 50 cent, mintage: 23,287,000, $4.00
  • 1988 First Fleet Bicentenary 50 cent, mintage: 8,990,800, $15.00
  • 1991 Decimal Anniversary 50 cent, mintage: 4,704,400, $10.00
  • 1994 Year of the Family 50 cent, mintage: 20,830,800, $12.00
  • 1995 Weary Dunlop 50 cent, mintage: 15,869,200, $7.00
  • 1998 Bass and Flinders 50 cent, mintage: 22,426,000, $7.00
  • 2000 Year 2000 Millennium 50 cent, mintage: 16,630,000, $7.00

So these are the prices you can expect to pay for an example of these coins. When you come to sell them expect considerably less. If your 50c coins are not truly uncirculated expect to get offered face value (though you may get a little more if you try selling them on eBay).

You’ll find that some normal circulation coins have much lower mintages than the commemorative coins, and the fact that they were not hoarded means they can be worth a little more. And before I get onto those, the 1966 round 50 cent is not rare and nor is it particularly valuable. It does have real silver in it though which is different to all the other 50 cent coins issued and makes it worth a bit even if it is a banged up circulated coin. So what is the round 50 cent coin worth? It depends on the silver price of the day. You could take a look at our Aussie silver coin value calculator to work it out.

Anyway, back onto the circulation issues. Truly uncirculated 50 cent coins from 1969 (cv $25), 1971 ($25), 1972 ($55), 1973 ($60), 1974 ($35), 1985 ($13), 1993 ($22) , and 1997 ($30) are all worth more than any commemorative 50c coin. In fact some of the mintages are small by comparison, the 1985 and 1993 coins had mintages of less than 1 million and may be worth putting away for the future if you find them even if they have been circulated. In, fact, these days hardcore decimal collectors are looking for the best quality uncirculated 50 cent coins they can find for their collections. So, if you do have a sparkling UNC 1973 50 cent coin you might get a bit of money for it if you list it up on an online auction site.

In the next issue of this series I’ll cover some rare and valuable 50 cent coins you can look for in your change. These wont show up too often but they are worth keeping an eye out for.

Star Notes or Star Replacement Banknotes

Australia 1 Dollar Starnote

Australia 1 Dollar Starnote

Star replacement banknotes are pre-decimal and paper decimal notes with serial numbers ending with a star or asterisk. Thus being named a star note. These notes were issued from 1948 to 1972 in Australia. They were used to replace faulty, soiled or damaged notes during the printing process. They were introduced to allow sections of 100 notes to start at 01 and finish at 00 to assist tellers with counting notes. There was no longer a need for replacement notes after 1972 with the introduction of automated counting systems. These automated systems allowed a faulty note in a sheet to be marked with a special ink and after it was cut as it was being processed would be recognised and diverted away from the final bundle.

The USA began using the star replacement note system in 1910. Australia was slow to adopt the practice favouring to hand stamp the original serial number of a soiled note onto it’s replacement. The star note system was introduced in Australia in 1948 to replace this laborious practice. Star notes were produced in a special printing run and when a problem note was found it was simply replaced with a star note. These star notes were the ten shilling, pound and five pound notes. There were no ten pound star notes produced. The star on a pre-decimal star note is a hollow five pointed star, the star on a decimal banknote is actually a six pointed asterisk.

Decimal star notes were always printed with the prefix serial number Z and the following numbers corresponded to the denomination.
ZA for $1 ie ZAA 00001*
ZF for $2 ie ZFA 00001*
ZN for $5 ie ZNA 00001*
ZS for $10 ie ZSA 00001*
ZX for $20 ie ZXA 00001*

On average there was one star note to every 200-300 ordinary notes. $50 notes were introduced in 1973 and were followed in 1984 by the $100 note so there were no star notes issued for these denominations.

Brisbane Coin Fair Overprints – Collectable or Silverfish Food?

Brisbane Coin Fair Overprint

Brisbane Coin Fair Overprint

The Brisbane Coin Fair run by VP Coins (Vic Power) is by all reports an excellent coin show to visit. It is attended by a lot of dealers, held twice a year and many people say is a lot better than some of the ANDA coin shows held around Australia. For the show in February 2008, as a marketing exercise Vic overprinted 973 Coat of Arms mintmark dollar coin folders with “Brisbane Coin Fair February 2008”. Now these were just the general issue Coat of Arms “C” mintmark dollars in their packaging, but the folder was over-printed. He repeated this exercise in October 2008 (with COA “B” privy coins- 1089 issued) and again this month but with the new 60 Years of Australian Citizenship Dollar “C” mintmark. You can see one of the overprinted coin folders from this months show above, 1493 of these were issued at the show.

These overprint folders present an interesting conundrum to the collectors of Australian $1 coins. Namely, should you collect them or not? They are, after all, the same coins you can get in non-overprinted folders. So in reality all you are collecting if you do choose to get them is the packaging. There are really just three arguments for collecting them.

  1. Firstly, they are dollar related, and if one was to be pedantic, for completeness, then you do require them for a truly comprehensive collection.
  2. The second argument is the mostly unsubstantiated claim that these overprints are recognised by the Royal Australian Mint (in fact some of the production of the first overprint was supposedly done by the RAM). The claims are restricted to ‘someone read in the Australian Coin and Banknotes magazine that they were recognised’ and ‘the RAM is supposed to have an overprint in their museum’. Neither of these claims is particularly strong nor supported by any real proof.

    UPDATE 10 October 2015
    Vic Power of VP Coins in Queensland sent us some clarification on this point 6 years after this article was first published. Vic ran the Brisbane Coin Fair so if anyone knew the truth behind these issues then he would. Here’s what he told us:

    The overprint was always done by a foil printer in Brisbane and never by the mint. All overprints were approved by the RAM prior to printing. The RAM requested that we send them a couple of examples of the finished product for their records which would explain any that they may have on (sic) display.

  3. The final reason for wanting these overprints would be purely financial. These overprints are scarce, with just 1000-1500 printed for each show. They are available to people who attend the shows for just $6 or so, and sell on eBay for $20. The February 2008 overprint was getting $40-$50 at the peak of it’s prices.

Well what are the reasons for not wanting to collect them? Just one really. They are not a unique coin, they are just packaging. Silverfish food. As someone I know says, it’s just ‘packyboxitis’ on the behalf of collectors who want them. If you’re collecting these why not the other varied packaging that dollar coins come in, the various VIP issues, Berlin Coin Fair overprints, mint sets, proof sets, the list goes on.

What do I think? Well I have one of each of the overprints for completeness, but if the prices for them in the secondary market had reached exorbitant levels I would not have bothered. They are collectable and interesting, but I am not really sure they should comprise part of what I’d call an official dollar coin collection.

Rare Australian Decimal Coins: Part Two- Extreme Decimal Rarities

This is part 2 of a series on rare decimal coins that can be found in Australia. Interesting and extremely rare Australian decimal coins include the 1981 scalloped 20 cent which is a 20 cent design accidentally minted on a Hong Kong $2 planchet, there are 6 examples of these known to exist.

Occasionally a coin of a different year finds it’s way into a years mint or proof set. In a very few examples of the 2006 proof set it has been found that the dollar included was a 2005 mob of roos coin. Although it has not been officially recognized by the Royal Australian Mint it is a clear error, as there were no other 2005 proof mob of roo dollars released. The proof dollar minted for the 2005 set was the Dancing Man dollar. This Mule is definitely a rarity with only around 40 known sets to date.

A possibly unique error that surfaced at a Downie’s auction in 2007 was a bi-metal 20 cent piece. This was said to have been removed from an Armaguard security roll. The only practical explanation for this is that a foreign bi-metal blank got mixed in with a batch of our blanks which the RAM sources from Korea. This coin which cost it’s owner 20 cent was sold for $3600 + comm.

It is interesting when reading the RAM official mintage reports for each year, in 1988 a 50 cent Coat of Arms issue is just not mentioned. The issue for 1988 was the commemorative Bicentennial design. Surfacing in an IAG auction in August 2006 was just that, an accidental 1988 Coat of Arms coin selling for $5400 + commission. This has also happened in 1977 when the 50 cent was minted with a reverse design commemorating the 25th anniversary of the coronation of Queen Elizabeth. These coins can be officially labelled as mule error coins as they were struck from dies not intended to be paired together (for that year anyway).

Rare Australian Decimal Coins: Part One- Rare Coins in Change

There are many Australian decimal coins which are rare and scarce. Often it can be harder to find certain coins in circulation because for a particular year that denomination was low mintage. Examples of these are:

  • 1968 5 cent
  • 1972 5 cent
  • 1968 20 cent
  • 1997 50 cent

Legitimate variety or error finds that were actually released by the mint that are so scarce that if you actually find one in circulation then you should go out and buy yourself a lottery ticket! These include the 2000 $1/10 cent mule or the 1966 wavy 2 20 cent piece.

1966 20 cent with Wavy 2

1966 20 cent with Wavy 2


Some years coins weren’t issued for circulation but were found in mint sets, some of these coins have found their way out of the sets into circulation and might be found.
These include:

  • 1989, 1990, 1991, 1992, 1993 and 1995 20 cent
  • 1986, 1987, 1989, 1990, 1992 Coat of Arms 50 cent

Some coins just weren’t issued to be circulating currency but are the same size, weight and colour as those you would get given in change. The majority of these are one dollar coins and are issued as Non-circulating Legal Tender (NCLT) coins. You can get lucky and find them in change and this is rare indeed. Examples of these might include:

  • 2000 Victoria Cross dollar
  • a variety of mintmarked, privy marked or counterstamped dollars
  • Coloured Ocean/Land series dollars

Other rare Australian coins are errors, mistake coins that have usually had quite obvious mishaps during the minting process. These are usually found and destroyed by mint staff before they leave the mint but occasionally some escape. Sometimes these are off centre strikes (also called mis-strikes or broadstrikes) or even clipped planchet coins just to name a couple. Other errors quite often overlooked because of their obscurity are cuds on coins or metal peels. These are often interesting collector pieces as they are all different.

Double Struck Coin Error

Double Struck 1959 Half Penny

Double Struck 1959 Half Penny

An interesting class of coin error is the double struck coin. This type of error occurs when a minted coin is struck again by the coining dies before it has left the coining press completely. This usually results in a partial impression of the coin over the previously struck image.

For example, the image above shows a double struck Australian 1959 half penny. On the obverse you can see the remnants of the first strike showing from about 2 o’clock to about 7 o’clock in the area close to the rim. On the reverse you can see the remnants of the first strike from about 4 o’clock to 11 o’clock, again in the area close to the rim.

Below we can see a decimal double strike on a two dollar coin, there have been quite a few found with this date -perhaps there was a fault with the press at that time. An example like this would probably set you back $1000+

Double Struck 2009 Two Dollar Coin

Double Struck 2009 Two Dollar Coin

A very rare occurance is this error that has a mate out there somewhere. It was this coin that struck another coin
causing an indent with a brockage. The coin pictured below is double struck on the obverse with the doubled section being sandwiched against a blank coin still in the press.

1981 20 cent Double Strike

1981 20 cent Double Strike


All the coins seen here in this article are double struck out of the collar. This means when the second strike was applied the coin had disengaged and was partially or mostly on it’s way out of the press. The 2 cent seen below only just caught on the edge as it was leaving the press. Just visible on the obverse second strike is the top of Her Majesty’s head and the tip of her crown. The reverse shows just the tip of the lizards tail.

1980 2 cent double struck

1980 2 cent double struck

Scarcer types of double strike errors occur when the coin is still engaged in the collar. The coin has either rotated and failed to exit and is therefore stuck again or flips over landing back in the collar and is struck again. Read about these errors in our other articles –rotated double strike errors and flip over double strike errors.

The 2000 $1 / 10 Cent Mule

Australian 2000 $1 / 10 cent Mule

Australian 2000 $1 / 10 cent Mule


In 2003 Australian coin collectors began to become aware of a major coin error that had been released by the Royal Australian Mint. A number of the year 2000 $1 dollar coins had been minted using the incorrect obverse die (heads side) and released into circulation but the error had not been found for a year or two. The obverse of some of the 2000 $1 dollar coins had been minted using the Australian 10 cent obverse die by mistake. With just a 1.4 millimetre difference in diameter between the 10 cent and $1 coin the error went unnoticed, and the legendary 2000 $1 ‘mule’ was released into the wild.

The majority of the 2000 $1 / 10 cent Mules were sent to Perth, where in 2003/2004 there was a frenzy of ‘mule’ hunting in the local casino and lots of dollar coins were withdrawn from Perth banks. This was the height of the ‘mule’ season with enthusiastic searchers finding 1 or more mules each day spent searching. With the mules fetching several hundred dollars each at the time it was a profitable and enjoyable way of spending a day. The ‘mule’ hunt has slowed in the last few years as the number available in circulation is slowly reduced and diluted around the rest of Australia. But, the mules are still out there to be found by those willing to look. For example, the coin above was found by the author in early 2008 at the Burswood casino in Perth. Examples discovered these days tend to be lower grades, showing a lot of wear and scuff marks, but with even low grade examples worth $300-$400 they are still worth finding.

Spotting a 2000 $1 / 10 cent mule isn’t difficult when you compare it with a normal $1 coin. The smaller 10 cent die means that there is a large double rim around the obverse of the coin, this can be seen clearly in the image of the coin above. Because the smaller die was used the obverse strike is often off centre, and the double rim equally off centre. On the coin above the obverse of the coin above is shifted toward the top of the coin. Mules with well centered obverse strikes tend to fetch more money than those like the coin above.

Total mintage of the 2000 $1 / 10 cent mule is a matter of some conjecture. However, a number of the more prolific mule hunters shared their find statistics on the now defunct Aussie Coins internet forum. From these figures and the large sample size searched (some hunters looked through upwards of 2 million coins) it was deduced that the mintage of the 2000 $1 mule was around 6000-7000. The mintage of 400 stated in the Pocket Guide to Australian Coin and Banknotes by Greg McDonald is simply incorrect so do not take any notice of this figure. The inaccuracy of this number is shown by the fact that the total number of mules discovered Australia wide is far in excess of 400, with some hunters having found more than 200 by themselves!

So, the next time you’re at the bank, or in the local poker machine venue, why not look through those $1 coins. You’ll never know what you might find, and if you are lucky enough to find a mule, then all it will have cost you is $1 and some time.

The 1937 and 1938 Australian Crown

A 1937 Australian Crown

A 1937 Australian Crown

The silver Australian Crown was minted in Melbourne only in the years 1937 and 1938. It depicts an image of a royal crown on the reverse designed by George Kruger Gray and George VI portrait on the obverse by Thomas H Paget. It’s denomination is 5 shillings.

The Australian Crown was initially issued in 1937 to mark the occasion of the coronation of George VI. Many of these were hoarded as keepsakes of the occasion. Because of this popularity it was released again in 1938 but without much success. As a new denomination and a large coin weighing 28.27 grams with a 38.5 millimetre diameter it was considered too heavy and awkward to be carried for everyday usage. The 1937 crown has a mintage of 1 008 000 and the 1938 a mere 101 000 thus the 1938 is the rarer more sought after coin.

Because of the hoarding of the 1937 crown it is quite common to see these coins in mid-grade however rarely seen in the lowest grades and difficult to obtain in the highest grades. The highest point to note in the design when looking for wear is the cross in the orb of the crown and how distinguishable it is. Crowns are often found with heavy bag-marks because of the heavily reeded edge and the large fields.

The Australian One Dollar $1 Coin

Australia 2014  Mob of Roos Dollar

Australia 2014 Mob of Roos Dollar

A popular series for collectors and their collections is the Australian one dollar coins issues.The one dollar was first minted in 1984 when the $1 note was withdrawn from circulation. The reverse has the iconic 5 ‘mob of roos’ design by Stuart Devlin. It’s composition is 92% copper, 6% aluminium and 2% nickel which is nicknamed ‘alum bronze’. It is 25 millimetres diameter and weighs 9 grams. The one dollar coin is often released each year with commemorative designs depicting events of that year.

In 1991 the Royal Australian Mint introduced a new concept where if you visited the mint you could press your own coin on the gallery presses and keep the coin in a special folder. 1993 brought the first of the mintmarked $1 coins where a special letter was struck on the coin either at a show or fair. Also coins were released throughout the year depicting different letters. Often these mintmarks differed only very slightly and it was difficult to determine their origin. These mintmark dollars proved extremely popular with the public and the mint increased their releases to include other alum bronze collector dollars the same size and weight that weren’t for circulation. Because of their size and similarities to the circulation dollars they are often found in circulation and are eagerly sought after by ‘coin noodlers’. A particular example is the 2000 Victoria Cross dollar which was issued in a special folder at $5 and now retails for $250. These have been known to turn up occasionally in poker (or slot) machines.

Australian 2000 $1 / 10 cent Mule

Australian 2000 $1 / 10 cent Mule

In the year 2000 there was a mistake at the Royal Australian Mint during production of the dollars. The “mob of roos” reverse die was accidently partnered with the Queen Elizabeth II obverse die of the Australian 10 cent piece. This 10 cent die was only slightly smaller than the normal dollar obverse die. Coins were released into circulation and to numismatists delight the error was found. These dollars could easily be found in change so the “mule” hunt began. An average example of a mule today could be worth $400 and a high grade example worth $4000.

2006 brought more interest to the one dollar series with the RAM incorporating a new method of production; the pad printed design. This colored series featured ocean animals and is very popular with collectors. Now you would surely notice if one of those ended up in your change! These are NCLT issues not intended for circulation. Read more about this in my previous post.

This year the RAM did a rethink of the term mintmark and introduced some other terms to help distinguish between the dollar coins and where and how they were struck. The terms counterstamp, privymark and mintmark are now used. You can learn about the differences of these coins in my previous post here.

To date there are over a hundred different types and mintmarked coins possible to collect of the 25 millimetre dollar. To collect the entire series of the alum bronze dollars takes a lot of effort and with the mint issuing more and more every year it is becoming difficult on one’s wallet keeping up with them all. A new scheme the RAM has come up with involves putting unique dollar designs in mint sets or uncirculated baby sets, forcing collectors to purchase the entire set and break it up just to get the dollar coin. Some of these newer releases seem to be really just novelty coins and haven’t proved successful for investment purposes. I might have to rethink my collection……….

Australian 1966 Round Silver 50 Cent

1966 50c, Round and 80% Silver

1966 50c, Round and 80% Silver

The round Australian 50 cent piece was introduced at the changeover to decimal currency in Australia in 1966. It is 31.5 millimetre and a round shape, the only round 50 cent piece, containing 80% silver and 20% Copper. Weighing 13.28 grams with 0.3416oz of silver it wasn’t long before the value of the silver content far outweighed the fifty cent face value and it was withdrawn from production and replaced in 1969 with the dodecagonal (12 sided) shape. Despite them being withdrawn from circulation many millions of the coins were hoarded by the Australian public and the coin entered the popular folklore.

To the numismatic newbie or the general population it is falsely regarded as a rarity, in fact there were 36 454 000 coins minted, although many have been returned to the mint and melted down. These today are generally traded as bullion coins rather than being traded as collector coins. Higher grade examples are readily available but you can expect to pay a fair bit more than the bullion value for these coins.

The reverse design on the 1966 round 50 cent is the Australian Coat of Arms by Stuart Devlin. The obverse is the young portrait of Queen Elizabeth II by Arnold Machin.

A well known variety of the 50c piece is the double bar variety. Incorporated in the original design were 2 horizontal bars in the reeding behind the emu’s head. These bars could possibly cause weakening of the dies during striking so were probably ground off the transfer punches that were used to make the dies, but not on all of them.

In celebration of the 40th anniversary of decimal currency in Australia the RAM produced their 2006 sets with the original round shape 50c piece.

You can work out todays value of your 1966 round silver 50 cent using our Australian Silver Coin Value calculator.

The current value of a round 50 cent coin is AUD $17.51. This value is updated every hour or so using the current silver price and exchange rates from Currency Layer.
