1 Dollar - Elizabeth II Copperband Butterflyfish

Issued under Fiji's broader wildlife commemorative program, this piece was struck in gold-plated copper-nickel as a lower-cost variant alongside a pure silver version — a common dual-release strategy by the Perth Mint, which produced the series. The copperband butterflyfish is native to the Indo-Pacific reefs surrounding Fiji, making it a locally relevant subject rather than an arbitrary exotic choice.

The gold plating on copper-nickel examples is notoriously thin and prone to wear at contact points, even in uncirculated condition.
