50 Cents - Elizabeth II 6th Portrait - Gold Proof

The sixth portrait of Elizabeth II, sculpted by Jody Clark, was introduced by the Royal Mint in 2015 and adopted progressively across Commonwealth issuing authorities — the Royal Australian Mint being among the later adopters. Clark was a relatively junior engraver when selected, and his portrait was the first designed by an internal Royal Mint staff member since the 1960s. The Australian 50-cent denomination is notably unusual for gold proof issues of this weight class, given that the circulating coin is dodecagonal and base-metal; the round gold proof format exists entirely outside normal production parameters.
