10 Dollars - Elizabeth II Simpson and his Donkey

John Simpson Kirkpatrick — a British-born Australian soldier who used a donkey to ferry wounded men from Anzac Cove during the Gallipoli campaign of 1915 — was killed by shrapnel on May 19, just weeks into the campaign. He had been AWOL from his unit to carry out the work. Kiribati, a Pacific microstate with no historical connection to Anzac, issues these pieces almost entirely for the collector market, a practice common among small island nations leveraging their mint authority for numismatic revenue.
