50 Dollars - Elizabeth II 4th Portrait - Native Frangipani - Platinum Proof

Part of Perth Mint's native flora platinum proof series, this issue draws on Australia's long-running program of bullion and numismatic platinum coinage that gained serious collector traction through the 1990s and 2000s. The pad-printing technique used here — applying color directly onto the coin surface rather than through traditional enameling — was still relatively novel in Australian numismatics at the time of issue, and early examples from the series show minor variation in ink adhesion at the petal margins.
