The Money at the Bottom of the Sea

On the Pacific island of Yap, money came as huge stone discs, some taller than a person, carved from rock on islands hundreds of kilometres away.

The stones were too heavy to move, so when one changed hands, it usually stayed put. Everyone simply remembered who owned it.
