Yapese Rai

Origin
Rai, or stone money, are large, circular stone disks carved out of limestone formed from aragonite and calcite crystals. Rai stones were quarried on several of the Micronesian islands, mainly Palau, but briefly on Guam as well, and transported for use as money to the island of Yap. They have been used in trade by the Yapese as a form of currency.

While the monetary system of Yap appears to use these giant stones as tokens, in fact it relies on an oral history of ownership. Being too large to move, buying an item with these stones is as easy as saying it no longer belongs to you. As long as the transaction is recorded in the oral history, it will now be owned by the person you passed it on to—no physical movement of the stone is required.

The names of previous owners are passed down to the new one. In one instance, a large rai being transported by canoe and outrigger was accidentally dropped and sank to the sea floor. Although it was never seen again, everyone agreed that the rai must still be there, so it continued to be transacted as genuine currency.

Effects
This large stone Rai is assumed to be the artifact in question. Whenever it is mentioned in regards to a transaction, the seller will immediately accept it as a form of payment, regardless of how aware they are of it. It has a physical presence and on at least three occasions has manifested a total sum of $78.50 into the accounts of it's current owner.

It was discovered after Claudia Donovan mentioned it whilst paying for her daily coffee in a conversation to another agent. The till glowed with artifact energy and the payment went through, transferring ownership of the Rai to the barista. The Rai enters a default state if the current owner dies, allowing anyone to claim it. Due to it's location, recovery is impossible, though this seems to be a non-issue regarding it's effects.

Currently the 'owner' is Mrs. Frederic.
