1 Dollar - Elizabeth II Tasmanian Tiger

The thylacine, declared extinct in 1936 following the death of the last known specimen at Hobart's Beaumaris Zoo, has become one of Australia's more commercially durable numismatic subjects. Perth Mint has returned to the animal repeatedly across bullion and collector series, and this 2011 dollar sits within a broader run of Australian wildlife-themed one-ounce silver issues that began gaining serious international traction in the early 2000s. KM#163 cross-references a crowded catalog — Perth's output during this period was prolific enough that attribution without the reference number invites confusion.
