I found this dime the other day which seems to have a little "bubble" but with absolutely no abnormality on the opposing side. I know excessive heat can cause bubbles, but the P seems to be stamped into it. Thoughts and opinions?  Edited by SlyCynic

So it's a fairly common thing? Bit of a noob here...

Plating bubbles aren't unusual, although this one, nearly under the mint mark, would have made me look twice, too.

Dimes are not plated. They are clad layered. This one looks like it was over polished in that area. reducing the field on the die, raising the surface on a coin.

There can be a gas bubble in clad coins go to error ref.com it will explain different type of planchet error.

I indeed misspoke using the term "plating" as dimes are clad. I still feel it is a bubble however.

Note the weakness of the mint mark. See the upper side of the mint mark is missing near the area in question. There was a very heavy deep die polishing on that field area that removed the deeper device in that area.

To me if was overpolishing, the mint mark would flow into the polished area. Here it appears to be clearly seperate from not only the mint mark but the bust as well.

If you take a toothpick and gently push in if it dents the spot it is a bubble,but from what I have been reading some bubbles are firm and won't leave a dent.
