25 Dollars - Charles III PZL P.1

Pobjoy Mint's PZL designation marks this as part of their proprietary plano-zirconia lens series, where a synthetic gemstone is pressure-set into the flan before striking — a technically demanding process that causes meaningful rejection rates during production. Niue has served as Pobjoy's primary Pacific issuing authority for collector issues of this kind since the 1990s, functioning essentially as a licensing arrangement rather than reflecting any domestic monetary need.

Charles III's accession coinage flooded the collector market through 2023–2024 across dozens of issuing territories simultaneously.
