25 Dollars - Charles III 1st Portrait - Australian Kangaroo - Gold Bullion Coin

Australia's Kangaroo gold bullion series, running continuously since 1986, is one of the few sovereign bullion programs that changes its reverse design annually — a deliberate policy introduced to discourage melting and encourage collector retention alongside investment demand. The Perth Mint operates under a Western Australian government guarantee rather than a federal one, a distinction that occasionally surprises buyers expecting Reserve Bank backing.

Charles III's first portrait on Australian coinage, sculpted by Dominic Endean, entered circulation following the standard inter-regnum process coordinated through the Royal Mint in London.
