2014 Proof SetAustralians have been carrying around Stuart Devlins kangaroos in their pockets for thirty years. The design on the reverse of the $1 coin became a favourite of collectors when it was introduced as a replacement for the discontinued $1 note in 1984. This six coin Proof Set features a selectively gold plated $1 coin as its centrepiece, pressed for the first time on a cupro nickel blank.
