All of these were found on the bottom of New England rivers. If only I was better at researching them, My wife just got me Blocks book but the going is slow.
I am gonna go with Joe and Bostaurus on this one as all were found in either underwater dumps or in popular swimming holes, maybe they had them in their shorts when they jumped in. The 50 or so I recovered this summer were all under a foot bridge and mixed in with bottles and coins from the 1850's. This shot is my first batch of recoveries from this past summer, all were found in the same area.
