The object that you found appears to be a jetton rather than a actual coin. A jetton, counting caster used in accounting and mathematical calculations, are often similar to coins as they feature the profile of ruling monarchs. They are usually a copper alloy however can be pewter. Although I have not found any at the Indian River Inlet, I have found 2 without a detector, at the site of the Roosevelt Inlet Shipwreck. The Roosevelt Shipwreck, which sunk in 1774, was a commerical ship containing goods such as ceramic, wine, utilitarian wares to be sold in Philadelphia. It did not carry gold, silver or other precious commodities. The Louis XV jetton, which is the same as the ones that I have, have the words RECHEN PFENING in German, which means reckoning penny. The IAD indicates that Nuremberg guild masters from the 18th century who crafted them. The jetton also have been found with King George II (1727-1760) likeness.
