10 Dollars - Elizabeth II 3rd Portrait - Kookaburra - Silver - High Relief

The Kookaburra bullion series launched in 1990 as Australia's answer to the Canadian Maple Leaf and American Eagle, but the high-relief strikes issued for 1992–1993 represent a deliberate departure from standard bullion production — the dies were worked to produce greater depth of field, a process that demanded slower striking speeds and significantly higher per-coin production costs. At 311 grams, these required multiple blows from the press rather than a single pass.

The Royal Australian Mint competed directly with the Perth Mint's own silver programs during this period, a rivalry that shaped mintage decisions and premium pricing throughout the early 1990s bullion market.
