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

The "Great Aussie Coin Hunt" was a Royal Australian Mint circulation campaign launched in 2019 that flooded Australian commerce with 26 themed dollar coins — one for each letter of the alphabet — each representing an object or creature associated with Australian life. The program was explicitly modeled on earlier "A to Z" campaigns run by the Royal Mint of the United Kingdom in 2018, which generated substantial public engagement and secondary market activity. The silver proof versions were struck concurrently for collectors, sharing the reverse designs but finished to a standard the circulation pieces never approached.

Letter I stood for "iconic Australian animals" — specifically the ibis, a bird that has become an unlikely urban symbol in Sydney due to its aggressive scavenging around public spaces.
