I'm back! Had a lot of fun down at Mammoth Cave and even got to put a bat net right across the historic entrance. Had to pivot it out of the way for the last tour group to get out so I didn't net them. It was "bat night" and they had live night vision cameras on me at the net so tourists could watch the action from the surface and then I sent the bats up top for them to see the processing.
So I'm fairly sure this coin was originally a clamshell lamination split which was bent back and forth until the flake came off. Makes it look like a more expensive error than it is, but didn't pay much for it so picked it up while in Kentucky.
