10 Dollars - Elizabeth II Hello Kitty

Cook Islands has issued legal tender novelty coinage under licensing agreements for decades, with Hello Kitty appearing across multiple precious metal formats since at least the 2010s. This platinum strike falls into the fractional category — a 1/40 oz piece, essentially the smallest practical size for a struck platinum coin — produced almost entirely for the collector and gift market rather than any bullion purpose. Sanrio's licensing terms require design fidelity, which constrains die engravers to reproduce the character at a scale where detail resolution becomes a genuine technical challenge.
