5 Dollars - Charles III Superman

Niue has operated as a prolific licensing hub for themed bullion since the early 2000s, leveraging a 1990 currency agreement with New Zealand that permits it to issue legal tender without maintaining a central bank. The Superman licensing arrangement with DC Comics follows a well-worn commercial model — the coin's legal tender status is nominal, the real market is collector premiums.

The two-troy-ounce specification places this squarely in the mid-tier bullion-collectible category that spiked in demand after 2020 silver price volatility drew new buyers into the branded coin market.
