I was looking through my rolls of wheat cents the other day and noticed that a good deal of them had green spots on them. I immediately removed the coins with corrosion/damage and set them aside. I have been keeping them all in plastic tubes. My questions are: 1. Are all the tubes compromised, and do I need new ones? 2. What is the best way to remove the damage from the coins? They are common date cents, and I'm open to experimenting. 3. Could the other cents that were in the rolls that didn't have spots develop spots later, even though I removed the other cents.

Put the coins in a jar of virgin olive oil for a time. Agitate and check periodically.

Jason , you need to read how our members use pure acetone to help with your problem. Go to the, "Search Coin Community", box and punch in acetone.

No, this may work for Ancient Coin but, @ Ken, welcome back. CCF members have found a better method for restoring modern coins using a dip or soak in pure Acetone. There are some variables when to use it but, there is a good discussion in the forum. Look it up.

Without viewing your coins I'll stick by my original method of Acetone then Verdi-Care .

Be careful with acetone it can change the color of copper according to a professional conservationist.
Definitely get new tubes though they're cheap enough to not risk it

I do Acetone soaks all of the time. I only do soaks for 4 hours though. Just don't leave them in Acetone too long.
Errers and Varietys.

I've been using Acetone on Copper coins for well over 60 years now. Never had the color of the coins changed. I would like to know who this so called professional is.

Next most contain a mild Acid which is not good for coins. Please remember. Saying Olive Oil is like saying soap. Lots of different kinds.

I have never had any problems with the olive oil method. I wasn't aware that acetone could take off verdigris. I was under the impression that it takes off the plasticized gunk that remains on coins from cheap holders. EAC collectors have been using olive oil for years with great success. I will pick up some acetone and give it a shot.

Thanks everyone for the advice. I keep forgetting the bag I put all the cents in to take pictures, but it sounds like I need to soak them in acetone. I'll pick some up soon, and get more tubes. I did some research on verdigris, and that's exactly what is on the coins.

I believe it is only an issue for RED copper and even then under specific circumstances involving exposure to direct sunlight. It has been discussed before, I will see if I can find it.

Thanks JBuck. I will try acetone. I finally got around to taking a picture of a few of the cents. You can see the green spots I was talking about.
