15 Dollars - Elizabeth II 4th Portrait - Small Leaf Lillypilly - Platinum Proof

The Lillypilly series drew from Australia's native rainforest flora at a moment when the Royal Australian Mint was aggressively expanding its bullion and proof platinum program. The small leaf lilly pilly — Syzygium luehmannii — is endemic to coastal Queensland and northern New South Wales, a deliberate counterpoint to the eucalyptus-heavy iconography that had dominated Australian numismatic flora for decades.

Pad printing on platinum at this scale was technically demanding; the process allowed color application that conventional die striking cannot achieve, but adhesion consistency on .9995 fine platinum presented quality control challenges that limited mintage figures sharply.
