1 Dollar - Elizabeth II 4th Portrait - The Great Aussie Coin Hunt - Letter Y - Silver Proof

The Great Aussie Coin Hunt was a Royal Australian Mint circulation campaign that seeded 26 lettered one-dollar coins into everyday change across the country in 2019, each letter paired with an Australian cultural reference. The program was modeled loosely on similar alphabet-series promotions run by the Royal Mint and others, but was notable for achieving genuine public engagement — shortages were reported at banks within weeks of release.

This silver proof version of the "Y" coin was struck separately for collectors, never intended for circulation. KM#3652a distinguishes it from the base-metal circulation strike catalogued under the parent number.
