The 1977 Coat of Arms 50c is the rare one. They were not meant to be minted but 10 of them have appeared.
A list of valuable 50c Australian coins is fairly short - most are only worth their face value unless they are in premium grade. One of the first 50 cent piece designs that many people notice in their change are the fifty cent coins struck for the Centenary of Federation - there is one for each state and territory.
What are the rarest silver 50 cent coins? If you don't count over-dates, proofs, and strange varieties then the rarest half dollar coin is the 1873-S with no arrows. None of those coins are thought to have survived. The rarest coins that still exist are the 1796 and 1797 halves.
And the silver crisis of 1945 and 1946 and the 1945 Penny, Australia's rarest penny. And this 1946 cupro nickel florin, an experimental strike in an alternative metal and the the only example held by a private collector. The Melbourne Mint produced four florins in cupro nickel.
While it is unknown how many of the 1977 mules exist, with estimates of under 10 and catalogs noting seven known examples, it is indeed a rare and desirable coin.
According to the NGC Price Guide, as of June 2023, a Kennedy Half Dollar from 1979 in circulated condition is worth between $0.60 and $0.75. However, on the open market 1979 Half Dollars in pristine, uncirculated condition sell for as much as $315.
Which Australian One Dollar Coins Are Valuable? Australia's rarest one dollar coin is the 2000 $1/10c mule - this is the one to look for! A few years ago, a mint condition example sold at auction for more than $10,000.
The 1925 penny is Australia's 2nd rarest penny and is one of the most sought after coins in the entire penny set. Royal Mint records seem to indicate that it was struck quite late in 1925, mainly to make sure there was no chance that Australian shop tills ran short of pennies over the 1925 Christmas break.
It's important to note that only the John F Kennedy 1964 half dollars are composed of 90% silver, so be sure to check the dates on these coins to ensure that you're buying or selling silver coins as opposed to nickel-copper coins.
The round fifty cent coin was the highest-denomination and largest diameter coin of the Australian decimal coins, introduced in 1966. It has a nominal value of half an Australian dollar, the equivalent of five shillings in pre-decimal currency.
Some of the 2010 50 cent coins were minted with the obverse and reverse die rotated 30 degrees or one face of the dodecagonal shaped planchet. Presumably this was in error.
This is a scarce die variety of the coin, with only around 200,000 manufactured. It is well worth looking out for in your change as they can still be found, and they are worth $20-30 in average circulated condition.
You can see the Numisbid images of the coin above. This is for a coin with a McDonald's catalogue value of $5, from a proof set with a mintage of 80,000. The set itself has a catalogue value of $50 but in the real world 1983 proof sets can be had for less than twenty dollars.
The set was originally sold for $170 - however in recent days, the sets have been valued at as much as $6,000. Kandiah says it's the demand for the $2 Mars coin is driving the huge spike in price for the collection.
You won't find too many 1 cent coins on a list of Australian coins worth money - some 1 cent coins can be worth (much) more than their face value if they are a rare date and / or if they are in mint condition.
The reality is that unless you started collecting the coloured $2 coins in 2012, you are unlikely to find anything that has much value. It is possible to find the odd needle in the haystack, but it's uncommon that you're coloured $2 coin has any significant value.
1849 Double Eagle Gold Coin
The one remaining specimen is carefully preserved at National Numismatic Collections at the Smithsonian Institution. The 1849 Double Eagle is currently the rarest and most valuable coin in the world, with an estimated worth of nearly $20 million.
The title of Australia's rarest penny, while many think it's the 1930 penny, actually goes to the ones made at the Melbourne Mint in 1945. Featuring Thomas Humphrey Paget's effigy of King George VI and the jumping kangaroo reverse, only four pennies were produced at the Melbourne Mint that year.
According to the NGC Price Guide, as of June 2023, a Kennedy Half Dollar from 1980 in circulated condition is worth between $0.60 and $0.75. However, on the open market 1980 P Half Dollars in pristine, uncirculated condition sell for as much as $110.
