1 Dollar - Elizabeth II 4th Portrait - Australian Kookaburra - Gilded

The Kookaburra silver bullion series has run continuously since 1990, with Perth Mint issuing a new reverse design each year — a deliberate strategy to drive collector demand alongside the coin's bullion value. The 2006 gilded variant applies 24-karat gold selectively over the fine silver field, a post-mint treatment that Perth Mint offered as a premium finishing option during the mid-2000s when gilded bullion issues briefly proliferated across Australian and international programs.

KM#886a denotes the gilded version as a catalogued variant distinct from the standard strike, though both share the same planchet specification.
