Specifically, a 1983 Spanish 50 pesetas. My dad brought it back from Spain, he was in the air force reserves and they did some sort of civil service deal there. All that to say that the sentimental value FAR exceeds it's numismatic value. My question is how do I deal with what appears to be verdigris? I'm concerned with preserving the coin, but couldn't care less about any numismatic value... Here's a pic, tried to show the green as much as possible... Maybe looks a little worse in hand...  |

Acetone to start. Verdi-Care may help.

Copper-nickel verdigris always seems to leave a permanent stain on the coin, in my experience.
If you do as @Chute72 suggests, it will not hurt and will stop any further damage to the coin once it is put in the 2x2.

I will give it a try! Want to keep it from getting worse for sure, and I think it would look better without the green even if it does still have some "staining".

Just checking... this is what I want to use, right?  |

Answered my own question. Tried it on a dirty clad dime from my change... Turned out good so I dunked the Spanish coin. That one turned out good too! There is some staining, but the green is gone! I would say there was a 95% improvement!

Success.  Does that can say it is 100% pure? You can always test it by putting some in a clean glass bowl (with nothing else) and let it evaporate. If there is any reside left behind, I would not use it. |

I've never seen that brand of Acetone. Should be OK but any Acetone should be checked just in case.

Now make sure you dispose of it safely. If you pour it back into the container, you will contaminate the coins in your next batch.

I agree. Never reuse the acetone. Ideally, you should rinse the coin a final time in a fresh pour of acetone to make sure no particulates redeposited as the original batch evaporated.

Correct. Used acetone can be mixed with water and left out to discourage chipmunks.

Thanks, guys! I did try the evaporation test first, and dipped a random dirty dime from pocket change before I gave the Spanish coin a bath...
I may try some verdi-care too just to make sure the verdigris doesn't come back...
