10 Dollars - Elizabeth II Roaring Lion

Niue's arrangement with the New Zealand Treasury allows it to issue legal tender coins with no obligation to produce circulating coinage, making it one of the most prolific bullion licensing territories relative to its actual population of roughly 1,600 people. The 5 oz .9999 fine silver format places this squarely in the collector bullion category that expanded aggressively through the 2010s as mints competed for the premium stackable market.

Without confirmed specifics on the Roaring Lion series' mintage cap or issuing mint, the more useful note is this: KM#3942 attribution in Krause places it within a dense cluster of contemporaneous Niue silver issues, many of which share dies or planchet contracts with the Perth and New Zealand mints.
