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 & UNC 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)
