This is truly a find of a lifetime for me. Found at just 4 inches in modern park, and it sounded just like a modern penny (VDI +53).
Had it graded by a pro at VF-20, which, undamaged, would list at about $2500. (I did a little damage and there is other damage from 200 years in the ground). It is still a pretty coin, and I am quite happy with what I was offered for it.
