10 Dollars - Charles III Maple Leaf

Five-nines gold — .99999 fineness — is not merely a marketing tier. Achieving it requires an additional refining pass beyond the standard four-nines bullion threshold, and the Royal Canadian Mint has held the technical capacity to produce it consistently since the 1980s. The Solomon Islands issuing authority is a legal fiction here; these are Canadian Mint products sold under Pacific sovereign licensing, a common arrangement for fractional bullion series targeting collectors who want legal-tender framing without domestic mint infrastructure.

At 0.311 g, this is the smallest viable strike in the Maple Leaf program.
