This item feels nonmagical, and appears to be a normal gold piece. An identify spell reveals this item's true nature.

When this item is put in a purse with other gold coins, the coins slowly and mysteriously disappear over the course of 2d4 months, as long as nobody is looking at the purse at the moment a coin disappears. This item never disappears. If this item is placed in a purse without any other coins in it, this item disappears when nobody is looking at the purse. There is no other way to destroy this item.
