25 Dollars - Elizabeth II Scrooge McDuck

Niue has issued licensed Disney bullion coinage since 2014 under an arrangement that makes the island's treasury one of the more unusual royalty-payers in the Pacific. This McDuck piece belongs to a sub-series leaning directly into the character's numismatic identity — a duck whose entire fictional mythology is built around a personal coin collection and a bin full of currency. The joke writes itself, and the mint knew it.
