10 Dollars - Charles III 1st Portrait - Australian Kookaburra

The Australian Kookaburra series launched in 1990, making it one of the longest-running silver bullion programs in the world. Each year's reverse design changes — a legal requirement built into the program's structure to drive annual collector demand — while the obverse portrait cycles with the reigning monarch. This 2025 issue is among the first 10-dollar Kookaburra coins to carry the Ian Rank-Broadley replacement portrait of Charles III, commissioned following the accession in September 2022.

The 10 oz format entered the Kookaburra lineup to satisfy wholesale bullion buyers who wanted a larger vehicle in the same legal-tender framework.
