Comments

One of the coins introduced in 1966 at the commencement of decimal currency is this iconic Platypus 20 cent coin. The reverse was designed by Stuart Devlin. The coin has remained in production and circulation with the same reverse up to the current date and is now on its 4th Obverse. (Machin, Makleouf, Rank-Broadly & Clark)

These are images of the first Proof & BU Set containing the coin in 1966.


No Proof or UNC Sets were produced in 1967 or 1968.

While many millions of 20 cent coins were minted in 1983 & 1984, almost the entire production run was melted down and exported as base metal cupro-nickel bars due to lack of demand. Only one x $200 uncirculated mint roll box of each year has surfaced to date. So while nearly 83 million were minted in these 2 years combined only 2,000 are known to exist.

A Fine Silver (.999) Proof version of this coin was included in the 2006 40 Yrs of Decimal Currency Fine Silver Proof Set. (See link)

The two different mintmarks on the 1966 coin, thanks to

The 1981 coins were struck at three different places:
 20 cents 1981 Canberra & Wales Mint (left picture) with 4 full thick claws of the platypus under the 2 of the 20
 20 cents 1981 Winnipeg Mint (right picture) with 3 full thin claws and 1 half claw there:



In 1966 the 20 cent piece was minted in 2 different locations. About half of those coins were minted in Canberra and half in London at the Royal Mint in Birmingham. Of the 30 million coins minted in London just one of the dies that were used to press those coins was different.
The oddity is that one die had a small differing feature. This variety is in the base of the 2 of the 20 on the reverse of the coin. There is an upward curve in that baseline of the 2 often called a wave, thus the nickname the ‘wavy 20’ or ‘wavy baseline 20 cent’. You’ll also note a corresponding indentation in the water swirl above the wave. By comparison the normal reverse 20 cent has no wave in either the base of the 2 or the water above the baseline.

This is an image of a Wavy "2" 1966 20 Cent coin.



These are images of the famous 1981 scalloped error coin struck on a Hong Kong $2 Planchet by the Royal Mint.

A 1978 Mule coin is known to exist. An Australian 20 cent obverse was paired with a Fiji 20 cent reverse.
