Well, I have seen others on E Bay for sale from the same shipwreck they are going for between $300-$400 each I didn't pay that as I bought it from the guy that found and salvaged the wreak I paid $75.00 for mine. The name of the ship was Vliegent hart here's what the ship looked like when in use The coin is slightly larger then a silver dollar and is made of almost pure silver
