Yap

Yap is a small island in Micronesia known for its traditional stone money called "rai." These large, circular stones, sometimes over a meter in diameter, are used as a form of currency and social status rather than for everyday transactions. The value of a stone depends on factors like history, size, and craftsmanship, not just size. Yap's society traditionally relied on these stones for major exchanges, like marriages or land deals, highlighting a unique system where wealth and reputation are tied to the history and significance of the stones rather than their physical form or ubiquity.
