Whew! Clearly they are damaged and probably should just spend them as quarters rather then go through the effort to save them. Also, clearly the holder is going into the trash.

I've read in the forum about cleaning, not to..., yet if you do, acetone. And then there's baking soda and deionized or distilled water, etc.

The moisture in the safe happened years ago and now, after seeing this, I'm going through to see if any other problems.

I am using Dry-Packs 300gm Dehumidifier Moisture Indicating Silica Gel Canisters now.

So, I'm seeking recommendations on how to handle this situation. I did not find anywhere else where this extreme of powder was shown yet saw it discussed as Bronze disease. Although, most examples were on the coin faces and more permanent looking.

Thanks!

Uh, looks like the holder was kept in a terribly humid place for months, or that there is a problem with the holder itself. It looks like verdigris and, yes, your best choice is probably to spend these quarters as IMO there is nothing you can do anymore to save these quarters (there are some chemicals I think called VerdiCare but I'm not sure if it wouldn't ruin the coins, plus I honestly think it isn't worth it for these quarters).

It would make a fun science project, but if you deposit them into your bank account, you're already 75% of the way to another BU set.

Ouch.

I would not waste any time on these. Spend or deposit them and do not look back.
Rest in Peace

To the Forum .

It is not my intention to contradict the opinions of others
But, If you like to keep those coins * as rescue coins *
Nothing to lose . dip .those coins into CLR for 24 hours ..
You will see what happens . maybe you will be surprised with the results .
At your risk ...only my opinion .

they're only quarters and if they survive the process still being identifiable as such, then why not have some fun in the 'don't try this at home' section?

Otherwise I agree that, for collecting purposes, these coins are completely written off. As pocket change they're still worth 25 cent each.

If that is what is decided then I would not try to argue against it.

Was the safe flooded? If it was only moisture that caused that, then I wonder what is in that album that caused that much oxidation, maybe a type of salt, or chlorine used to manufacture the paper. It almost looks like the coins and album were submerged in saltwater. Very scary sight indeed. I would empty that safe as soon as possible to check on anything else that's in it.

Many fire rated safes are designed to release moisture to protect documents. Some do so excessively.
