picked this up in some change back in 88 and it has been out of circulation since (because of me. I think this is some sort of miss strike or something of that nature.   It is a bit hard to describe what it is on those pictures and yes I never did clean it. On the front of the coin near the letters LIBE in the word LIBERTY is a mound of material that takes up some of the area on Roosevelts face where his nose is and is part of the mound bur the details are stamped on the mound and is visible. Now on the back of the dime over the O in ONE is another mound of material where PLU in PLURIBUS is located and the PLU is clearly seen on that too. But when you run your fingers over the front and back you can clearly feel those two raised mounds. Edited by Mikeymus

So the raised area on the front is basically the same raised area on the back.. my guess would be a gas bubble in between the clad layers but I'm not an expert so let's wait and see what they say

That probably explains why it was in the same area on both sides of the coin. But I've never run into this before I'm surprised the coin didn't rupture from the striking.

It could have encountered heat or something that made it expand post-Mint, which is how they happen. Another possibility is metal added for whatever odd reason afterward, playing with a brazing tool or something. Have you the ability to weigh the coin with an accuracy of 0.01g? A gas bubble would be the likely explanation if the weight is unchanged. |

The coin was probably heated in a fire after it was minted.

I don't have the ability at this time to weigh the dime since I don't own a digital scale. But double checking the "Bubbles" the nose and PLU exhibit "strike through" charachteristics. Which would probably be the bubbles pre existed the striking but then again I am not clear on how they do the clad in these coins in the first place.

Obviously postmint but it always fascinates me to try and figure out how this stuff happens.  |

How does that explain the strike through characteristics of the nose and the letters PLU? It's just odd that there are so many conflicting attributes about this coin.
And just now I just noticed it is also struck off center if you look at the rim front and back it is wider at one side and narrower on the other.
BTW is it also possible that the "bubbles" were caused by contaminants prior to cladding?

The heat from a strong fire make the cladding bubble on the coin. Note this thread https://goccf.com/t/72493Not conflicting attributes. You can see where the coin was at one time burned black and someone tried to remove the blackened surface. On the reverse you can see where the rim was worn down in the area you feel it was off center. Just a PSD coin. |
