1 Dollar - Elizabeth II Red-Back Spider

Part of Perth Mint's ongoing Australian wildlife bullion series, this issue appeared the same year the mint was expanding its colored coin program aggressively into Asian collector markets, where novelty silver with applied color commanded significant premiums over spot. The red-back spider — Latrodectus hasselti — is closely related to the American black widow and has been responsible for thousands of recorded envenomations in Australia, though no fatality has been confirmed since antivenom became widely available in 1956.

KM# 130 attribution places it within the broader one-dollar legal tender series issued under Royal Australian Mint authorization but struck entirely by Perth.
