2 Dollars - Elizabeth II 4th Portrait - Australian Kookaburra

The Australian Kookaburra silver bullion series, launched in 1990, changes its reverse design annually — a deliberate policy by the Perth Mint to encourage year-on-year collecting and discourage melting. The $2 two-ounce denomination was introduced as a premium option above the standard one-ounce coin, targeting investors willing to pay for lower per-unit handling costs on larger silver weight.

KM#879 spans three consecutive years with a shared design, an uncommon move for a series built on annual variation.
