Yap
Yap is known for its stone money, known as Rai, or Fei: large doughnutshaped, carved disks of (usually) calcite, up to 4 m (12 ft) in diameter (most are much smaller).The smallest can be as little as centimetres ( in) in diameter. Many of them were brought from other islands, as far as New Guinea, but most came in ancient times from Palau.
