1942 P Jefferson Nickel

Well Ill find out today. I'm getting it looked at. Don't want to get too exited especially since it was free. But I have a feeling it wasn't copper plated after minting process. The burn marks are probably after it was minted but the coin itself looks to be pure copper. where the marks are on the edge of the coin it melted 4 points on the edge and indented enough to notice that its copper more than surface thick throughout the coin. Its hard to see in the pictures. Also the burn marks looks like residual copper dust got melted onto the surface like gunpowder to metal.

You can't strip the thing of silver and them have it bigger and weigh more without the silver. you would end up with microscopic o larger swiss-cheese holes and pathways where the silver was taken out.

The only way I could figure that to work would be like I said earlier if it was used as the cathode or anode of a battery that maybe had 4 posts that coins fit into to stabilize them and little plast4es placed on them then filled with some form of acid, but then the details shouldn't be so clear.

tis a mystery.
