case987 New Member United States 2 Posts	Posted 04/11/2021 3:27 pm Hi Everyone, I received a couple jars of old coins from my elderly father recently. I came across this 1950 penny. It appears to have had some kind of chemical reaction on a portion of the reverse. Anyone know what would cause this? Report this Post to the Staff

EDIT: An acetone soak my loosen it up so you can remove it. Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.

coop Bedrock of the Community United States 62064 Posts	Posted 04/11/2021 4:00 pm I just remembered, they used to coat new coin in varnish to protect them years ago. I wonder if this was one of their attempts? They used to coat the coins in olive oil, but that was plant based and turned out to rot the coins surface. They used to clean the Silver dollars with Comet to remove tarnish. (Another disaster) Rub the coins with Baking soda. (Another disaster) Put them in Vinegar and baking soda. (Turn cents pink inf color, removed the original surfaces. Bought coins at a coin show, took them to the parking lot, and used Jewelry Polish on silver coins to make them look better. Then took them back in to sell to other Vendors. I just wonder how many things people use today, down the line, they will find out that, that was another disaster. Report this Post to the Staff

merclover Bedrock of the Community United States 10635 Posts	Posted 04/12/2021 5:15 pm not a mint error, just some sort of staining or substance on the reverse surface. Either way, it's post mint damage ( PMD). to the CCF! Report this Post to the Staff
