What is a Rai Stone?

 

Rai stones are large circular disks that are carved out of limestone, which were used as a form of currency on Yap; an island in Micronesia. These stones were huge and heavy, so the act of paying for something with them, was done by agreeing orally that a trade had occurred.

Each stones value is determined by its size, craftsmanship and history.
