10 Dollars - Elizabeth II Machu Picchu

Part of a broader Solomon Islands series issuing fractional gold pieces tied to UNESCO World Heritage Sites, these coins were produced with little connection to the sites themselves beyond licensing arrangements that became common among Pacific island mints in the 2000s. Machu Picchu received UNESCO designation in 1983, though it had been a Peruvian national monument since 1981. The one-gram format was driven entirely by bullion economics — keeping the face value nominally credible against gold spot while targeting the novelty collector market rather than circulation.
