Welcome to the 20c sub-forum for my quest to noodle a full set of circulating Australian decimal coins from scratch starting in April 2022.



The Australian 20 cent coin was introduced in 1966 and features a platypus on the reverse. For decades the lowest mintage standard 20 cent was the 1971 coin with a mintage of 8.9 million until 2019 when the first coin featuring the new effigy of the queen designed by Jody Clark (JC) came out with a mintage of less then 3 million.

The 2001 Centenary of Federation series (featuring the 9 different states and territories) with mintages ranging from 2-3 million are probably the most hoarded 20 cent coins and are becoming difficult to find in circulation these days.

1983-1993 are considered the "lost years" with any coins found with these dates on them regarded to have escaped from a mint set. 1983 and 1984 coins were melted down and although the RAM lists the 1985 and 1988 as having small numbers minted for circulation none have actually been sited.

1966 and 1981 have slight changes in design which I consider to be mint marks rather than varieties as there are official mint figures for these coins. (1966 Canberra & London; 1981 Canberra, Canada and Wales). Personally I have never been able to tell the difference between Canberra and Wales minted coins.

The 'holy grail' of 20 cent noodling is the 1966 wavy baseline variety which is extremely scarce in circulation these days, but hey there might be some still out there.

Some other varieties to look out for are the 2004 large head or "Pointy A" and the 2010 "bubble". I will point these out if and when I find them.

Not including varieties there are currently 66 Australian circulating 20 cent coins to collect.

Day 3

The first 20 cent noodle (a $100 bag) yielded all but 4 of the standard platypus coins (1972 and 1997 and the Canada and Wales minted 1981). There probably was a 3.5 claw coin but all the 1981 coins I found today were too worn to be absolutely sure.

Commemorative coins were harder to come by. I only found 2 of the 9 Centenary of Federation coins. I also found a 2010 taxation office coin and 2011 women's day.

I notice I left out a space for the 2001 Bradman coin (mintage 10 million). Naturally I didn't find one of these today.







Total number of 20 cent coins noodled: 500
Number of coins found: 49
Number of coins left to find: 17

Here's a look at the Canberra and London mint 1966 coins.

The Canberra minted coin has a gap between the tip of the wave and the head of the platypus.

The second coin is an unusually very nice 1966 London minted coin. Notice there is no gap between the wave and the platypus' head.

Excuse my ignorance ,you state you got a $100 bag? .
Is the 'bag' from the Comm Bank and just loose coins?
I can only get rolls of coins from the machine in the wall.

1981 20 cent varieties, I think


Top left - Canberra - 4 full claws, big nostrils the index coin - to the right Llantrisant - 3 to 4 claws and smaller nostrils (Look at the far left claw, looks a bit "reduced").
Bottom - Canada (Not so sure now, 3 claws, blunted first claw, big open nostrils


L to R - Canberra, rounded bold letters, strong eyebrow
Llantrisant - Thinner eyebrow, letters thinner and further from rim
Canada - weak strike and impression, strong round letters, eyebrow but overall a weakly struck coin.

Apologies for bad photos - none of these coins are rare or even scarce.

crab eater, I initially replied to your question here with photos of various bags and bundles of coin but since they were of other denominations I moved the post to the main Big Noodle thread:

http://goccf.com/t/419886

I don't have any 20 cent bags to show you because I noodled them today and didn't take any photos. But the coins came in a big bag containing 25x $4 sachets of 20c coins (hence a $100 bag). You have to ask for them at the counter. Some banks get angry if they think you are emptying the coin exchange machine leaving none for their "business" customers.

Hope this answers your question.

Princetane, reading that you would think it would be pretty easy to tell the difference between them but you need coins in higher grades to be sure. Even then I get confused between Canberra and Llantrisant.

That's right, they minted over 50 million of each.

Yet a 3.5 claw coin in uncirculated condition has a catalogue value of $170.

Thats only for one with a cud error on it, a standard coin is only worth a few $. According to my McDonald catalogue.

I am confident with my Canberra and Llantrisant coins as both are EF/AU but I will admit the Canadian one is a real shot in the dark as its only gVF and a weak strike.

Day 9

Noodled another $100 bag. Didn't find much of what I was looking for (only 2 new coins).

Not a single 2001 Centenary of Federation coin to be seen.

Still any day you find two 2016 change-over 20 cent coins is a good day.



This was the only platypus coin I found which I didn't already have


Found a grubby 2010 "bubble" variety that you certainly don't find every day.



Total number of 20 cent coins noodled: 1000
Number of different coins found: 51
Number of coins still to find: 15

Day 17

Noodled through $58 of 20 cent coins and only found 2 new coins.

Pretty grubby 1972 and 2001 ACT Centenary of Federation


Got a surprise in the last roll of the day: 7 very nice 2019 JC coins (our lowest mintage 20c)


Commemorative 20 cent coins have become hard to come by.

Total number of 20 cent coins noodled: 1290
Number of different coins found: 53
Number of coins still to find: 13

Day 20

Noodled another $100 bag of 20c and found half a dozen coins that I needed.

So many of the commemorative coins I find these days are extremely grubby like these WA CoF and 2003 Australia's Volunteers coins:


Here are some better commemoratives including Northern Territory CoF, 2011 Royal Wedding and 10th anniversary of International Year of Volunteers ( Did that coin really need to be made)


Found a Canadian minted 3 1/2 claws which is clear under my magnifying lens but my scanner/camera is not good enough to show it clearly in a photo. Will wait until I find a higher grade to show it, but it is crossed off my list.

Total number of 20 cent coins noodled: 1790
Number of different coins found: 59
Number of coins still to find: 7

I quite like it, would have been better to see some non Caucasian faces on it too. I am sure there are many Indigenous, Asian, Indian and Polynesian Australians involved in volunteer work too.

I think the Wills/Kat coin is the ugliest and did not need to be made. I mean its up there with the 1994 Family 50 cents as the most awful design so far.

I love COINS!!!
