This amazing artifact dates to around 2400BC. It is a ring from a shell and represents the currency in use during that time. The value of the piece was relative to it's size, the smaller rings of the shell were worth less and the larger rings worth more. This shell has been amazingly preserved over the centuries. It was recovered from an Eqyptian pyramid during an archeological dig in the 1930's. It measures nearly an inch across at the widest point. Amazing piece of history
