10 Dollars - Elizabeth II Lost Dutchman's Gold Mine

The Lost Dutchman's Mine is one of the most persistent treasure legends in American folklore, tied to the Superstition Mountains of Arizona and to a 19th-century German immigrant named Jacob Waltz — the "Dutchman" being a corruption of "Deutsch." Despite over a century of searches, no verifiable lode has ever been confirmed, and several treasure hunters have died in the attempt.

Cook Islands became a prolific issuer of small-denomination gold coins in the mid-2000s, targeting the collector market with themed series of this approximate fractional weight.
