15 Dollars - Elizabeth II 6th Portrait - Little Hero

The "Little Hero" belongs to Perth Mint's ongoing series celebrating Australian animals, issued as a fractional gold proof aimed squarely at the gift and collector market rather than circulation. The sixth portrait of Elizabeth II, by sculptor Jody Clark, was adopted by Australian coinage from 2019 onward.

The layered composition — .9167 gold plated over .9999 fine gold — is a production technique Perth uses to achieve color differentiation on proof surfaces without resorting to enamel or paint, keeping the piece technically all-gold.
