10 Dollars - Charles III Matterhorn

At 0.0622 grams, this is a fractional gold piece in the strictest sense — the Matterhorn series from various Pacific sovereign issuers has become a vehicle for minting houses, particularly the Swiss PAMP refinery and associated partners, to produce legal-tender miniature gold coins using Solomon Islands' issuing authority. The arrangement is purely commercial; the Solomon Islands bear no historical or geographic connection to the subject matter.
