Here is a 1942 S Mercury dime that has a bubble in the metal. Can anyone explain what happened during the minting process ?
Hold your ear real close to the coin. see if you hear: 'Lemme out, lemme out.' if so, follow jhinton's suggestion
What has been said about the heat being applied may be true. But then, there might be a bit of Artificial Toning around the bubble if they used a torch. If it was cooked it would show like yours. Besides, Mercury dimes were made with solid silver 90% anyway. Clad dimes have lamination errors because of it being made of seperate layers. As I said before, they are solid silver and dont have seperate layers. But then, during minting, the metal could have stuck to the die and a bit of metal protruded upword. But itis veery rare so i think this is PMD. Get ti graded by PCGs anyhow!
My 2 cents To me I see 4 mark on the rim that tell me at one time it was in a piece of Jewelry.and the blob on the rev my have keep it in place.:kewl:that is what I think
Based on looking at both sides, I think jello was at least half right. To me it looks like someone punched a hole in it to use it as a pendant on a necklace and then at some time tried to fill the hole back in (and did a crappy job of it). I've run into at least half a dozen silver halves with a hole punched near the rim.
