too oddly shaped to have been encased... plus if the encasement dug the middle of the rim out, as suggested, the amt. of force needed to push the center in like that... wouldn't that leave a dent or something in the devices of the reverse? even highly padded, it should have left a dent in the reverse that shows up on the obverse, don't you think?
This coin was altered outside the mint. The edge, which is concave in vertical cross-section, indicates that the coin was probably encased in a ring. It's certainly not the result of any minting error. The lack of copper plating is probably due to the plating being chemically removed. Finally, the proportional expansion of both faces is an impossibility in a genuine error. The coin was possibly pounded between two pieces of hard leather. These altered coins are known as "Texas cents". Most lack the plating, for some reason.
One thing is for sure it was a nice gift :hug: (Okay so she things your look weird and elongated but you can put up with that LOL)
