I am new to posting but have been lurking in the forums for a while now. Just recently got to collecting and would appreciate any thoughts on this quarter I found. It is the back of a dime on the face of Washington. I'm nearly certain someone pressed a dime onto the quarter but I wondered if it were even possible for a coin to be minted this way? Appreciate your thoughts and time.  |

 That would be an impression in clear glue from a dime. |

You can remove it by soaking the coin in acetone. |

Interesting. Never considered glue on a coin. I take it this is a common enough occurrence to be able to identify it?

Well, because the lettering is reversed, we can tell that it was done by the back of a properly minted coin. If the area is incuse, then a coin was forcibly pressed against your subject coin, either with a vice or a hammer. If the area is raised, then it's the reverse impression of another coin on surface residue, usually glue. Oh, and welcome!

Makes complete sense. Since it was the reverse of a coin I figured it couldn't have been minted that way but I was at a loss of how it could have gotten there. An impression I would have understood could be done with a vice or hammer but the raised surface threw me off. Appreciate the knowledge.
Thanks for the welcomes, hope to post more often!

Still interesting, how would that have gotten there like that. And using acetone.. wouldn't that be something you don't want to do on coins?

I don't know why people do it but we see it here every once in awhile. I suppose it happens by accident or people are making their own game tokens or something.
Acetone is - as far as I know - the only safe thing to use to remove foreign substances from coins. It must be pure acetone -- not nail polish remover which might contain oils and perfume.

And be careful where you get acetone. I got mine at Walmart in the paint section, under five bucks for a quart that will last me forever. Walgreens has "100% acetone" nail polish remover, but if you read the bottle, it lists denatonium benzoate as a secondary ingredient. I put that one back. It's a bittering agent, and I'm assuming it'll leave a residue on your coins. |

Practically any store-bought acetone and many other liquids will contain denatonium benzoate. Its concentration is so low it's negligible.

I agree with the posts above. And by the way, welcome, citation20! It sounds like you have a good understanding of coins already! It would not be impossible for a struck coin to be struck into anotger coin, and there are likely a few that exist. I can't find any photos right now though. Here is a quarter struck through a blank dime planchet: https://coins.ha.com/itm/errors/197...ption-071515 |
