5 Dollars - Charles III Summer Day

Niue has operated as a prolific licensing hub for commemorative bullion since the 1990s, contracting its sovereign issuing authority to third-party mints — primarily the Perth Mint — that design, strike, and distribute these pieces with minimal involvement from the island's roughly 1,500 residents. The resulting catalog runs into the thousands of types.

At 1.2 g, this sits at the lower boundary of what the Perth Mint typically produces in its fractional gold program.
