The listing, 1741 Mystery Coin - Unknown Origin has ended.
This coin is a mystery to me and, apparently, many others. I googled "1741 bronze coin ship crown" because they are the pictures on the front and back of coin. There are a few out there found all over the east coast. There is a lightweight similar coin that was found in a Barnes and Noble game, but some of these coins are heavier. I have been on a lot of treasure hunter sites and metal detecting sites and the consensus is pretty much the same. No one knows!
