2 Dollars - Elizabeth II 4th Portrait - Australian Kookaburra

The Australian Kookaburra silver bullion series, launched by the Perth Mint in 1990, was deliberately designed to compete with the Canadian Maple Leaf and American Silver Eagle in the international bullion market. Each annual release mandates a new kookaburra reverse design by law — a selling point that drove collector demand well beyond what pure bullion buyers would sustain alone.

The two-ounce denomination was a relatively short-lived experiment within the series, discontinued in favor of the more commercially viable one-ounce and ten-ounce formats.
