25 Dollars - Elizabeth II 4th Portrait - Kangaroo - Gold Bullion Coin

Australia's legal tender gold bullion program, administered by the Perth Mint under license from the Royal Australian Mint, has operated continuously since 1986 — making it one of the longest-running sovereign gold bullion series in the world. The .9999 fineness standard adopted for these coins was a deliberate commercial decision to undercut the South African Krugerrand's .9167 fineness and position Australian product as the purer alternative in Asian bullion markets, particularly Hong Kong and Japan.

The 2012 date saw the final year of Ian Rank-Broadley's fourth portrait of Elizabeth II before the series transitioned to Jody Clark's fifth portrait in subsequent issues.
