Thanks for the input friends. I have some further info regarding the displaced metal theory. This was my thinking also at first, but now I have doubts. Here is why. Displaced metal should be "movable" I would think. I put the coin under 60 power magnification and probed the extra metal with toothpicks. Nothing would budge at all. I am now convinced that the extra metal has been there from day one. As for "chips". This makes more sense to me, except the chips seem to have a bit of shape to them as opposed to just blobs of metal. Any way I thank you all and whee this is fun.
