15 Dollars - Elizabeth II 4th Portrait - Brolga - Platinum Proof

The Brolga series from Perth Mint occupied a quiet corner of Australia's platinum bullion program in the late 2000s, a period when the mint was aggressively expanding its collector-proof offerings across multiple metals simultaneously. The 1/10 oz denomination in platinum was primarily targeting the Asian collector market, where fractional platinum proofs in wildlife themes were finding consistent demand.

Ian Rank-Broadley's fourth-portrait effigy, introduced in 1998, appears here in its final decade before Jody Clark's replacement was adopted in 2015.
