10 Dollars - Charles III Batman #251

The Batman licensing arrangement behind Niue's ongoing DC Comics bullion program traces back to an agreement that has made this Pacific microstate — population under 2,000 — one of the more prolific issuers of pop-culture legal tender in the world. Niue's coinage authority is underwritten by New Zealand, which guarantees the face value, though no one expects these to circulate.

KM#6923 is one of several 5 oz silver issues in the series released under Charles III's effigy following the 2022 accession — meaning the obverse die relationship to earlier Elizabeth II issues in the same Batman run is a straightforward succession, not a redesign of the reverse program.
