Rock that is most probably a Native American produced and owned item. And a cool find. I am familiar with Johnlightning's part of the world and its history, as my ancestors were a big part of it. Do you think that's German Silver, John? Could very well be a native made item, as the tribes that were removed to the Indian Nations definitely had the capability to produce that sort of thing. Good argument for a fur trade item also. Most people don't know it, but French trappers frequented SE Oklahoma from a very early date, probably even before the removal. Note all the French place names and family names in SE Oklahoma to this day. Good find, John, and lookin forward to see what else you may come up with. You might post it over in the fur trade forum too and see what those guys think.
