Years back, I had a friend from Micronesia. We were at a bar and he was in awe of the bathroom token, as it was round and had a hole in the center. He told me all about the stone money. When he told me how they would carry these things on their boats, I asked what happens when the boat sinks. He said that the stone was still considered the owner's money, and was thus understood to be valid payment.
