Whytlash, Flip a dime and see if the bumps are in the same spot. Also they would have to have shot two different spots from inside the coin. WOLF

The "bump" does not align up so I don't think it's a bb gun job. Are the pix from the same coin? Is the bump raised on both obv.&rev.?

If the bump is sunken in on one side then it's marksmanship.
If the bump is bulged out on both sides, the coin has been subjected to high heat.

After further review? Is that the same coin(rev.&obv.)?Is one side a inie and one side a outie?  |

Well, when I first looked at it that is what came to me, as I've seen this before. I didn't look hard enough to notice that they don't line up. I was trying to discern from the angle of the pictures what was an innie and what was an outie. From the pics, it looks like the obverse has an outie and the reverse has an innie, as if the bb inpacted the reverse leaving an indent and the a raised lump on the obverse.
But now, looking a little harder, they don't line up, but are both raised bumps? If so then there is some other cause, perhaps as mentioned by coppercoins, if this is on the same coin. Never seen anything like that before.

Have seen halves like this before. Most of them had been through a fire. Does it have a seam around the edge where someone might have attached two different "halves" of the coin together?

Hi Wolf,
Yes they are. Both are about the same size and almost look like a BB. Some have said it may have been from extreme heating but there are no signs of heat on the dime and the surface on the exact oppisite side of each bump is perfect. I've never seen anything like it. Strange. Thanks, Jim

Could this be some kind of planchet flaw as far as metals not mixing properly and having some kind of reaction post mint? Maybe the chemists need to chime in.
Is this a dig find? If so, could something in the ground cause some kind of reaction in 6 years (assuming it's been buried since 2004)?

Not sure if this was dug or not. I would think it would take an aweful lot of heat to do this. I'm thinkin some kind of chemical got between the clad layers and created some sort of gas thats lifting the surfaces. WOLF

This has got to fall under the occluded gas and bubble category. Maybe there was just enough heat to cause the bubbles, but not enough to show as visible damage (other than the bubbles).
