2 Dollars - Elizabeth II 6th Portrait - Kookaburra Silver Bullion - High Relief

Perth Mint introduced a high-relief format to its Kookaburra series in 2020, requiring multiple die strikes per planchet to fully raise the design — a process that significantly limits throughput and accounts for the lower mintage relative to standard bullion releases in the series. The Kookaburra program itself dates to 1990, making it one of the longer-running silver bullion series from any sovereign mint, with the legal requirement that the reverse design change annually built directly into the enabling legislation.

The two-troy-ounce specification places this outside the flagship one-ounce tier, where secondary market liquidity is deepest.
