I posted some pictures last week of a handful of finds that included a completely slick quarter size piece of silver. On the back there were some markings but I didnt recognize them. Just this thursday I dug the 1794 dime size coin and noticed the markings on the back were the same. As it turns out the slick (almost) coin is a quarter size version of the dime size so I guess its from the 1700's also. 2 1700's silver in one week is almost impossible but here's the pic. Looks like it to me.
