Hey Group,

Earlier I was roll hunting and can across this beautiful coin and it had a very small green patch beside the head. I dabbed a cotton ball with acetone and real lightly tried to remove it. To my astonishment it turned silver. Did I remove plating that someone did? As far as I know this coin is supposed to be solid copper. I researched and found some 1981 cents struck on Dime planchet for sale and was wondering if that is what I have here. Thanks for y'alls help

They used copper planchets until the year 1982, sometime during the end of 1982 they went to copper plated zinc planchets due to the rising price of copper. Your cent is not plated and is copper. Weigh it, if it weighs 3.1 then it's copper, if it weighs 2.5 then you have a small fortune in your hand.

Why is it silver in color under the copper?

Whatever caused the discolor to begin with may have had a chemical reaction to the acetone used. That would be my best guess. I can say this with certainty, it is the correct planchet. It was not struck on a dime or nickel planchet.

Ok thank you Jim. Before I used acetone however, it was in pretty much uncirculated condition. No discoloration what so ever. Would it be smaller in size or something, it it were a Dime planchet? Or Nickel? Just curious. I'm just trying to understand. Thanks again Jim

Size and strike would not appear normal if this was a dime planchet. It's struck on a normal planchet. Most likely the acetone reacted with whatever was on the surface.

I hope we were able to fill in the gaps for you. There are many chemicals/substances that can change the toning on copper. You can take a magic erase pad and turn a copper coated zinc cent from copper to red/blue toning. After a while you can easily tell the difference in a chemically altered planchet and natural toning.

Coins also tone according to their surroundings. If it were exposed to something, it can alter the color of the coin. Areas where sulfur content is high can turn coins yellow in color. (affecting silver coins)
Moisture on copper coins can turn them green.
(Sorry no image)
Album storage can alter coins.

A BU cent in a album with the plastic slides.

Coins exposed to heat can alter the color.


Storing coins in envelopes can make them dark.
(Sorry no image)
Fingerprints:

Sneeze droplets can make freckles appear on coins.

Saliva can turn coin a darker brown.

Coins found outdoors and turn them a medium dark brown in color.

The area looks to be rectangular in shape, so there may have been something placed on the coin that reacted with the copper.

Probably not. If the plastic has PVC in the them, they will tone the coins also. Best to use the 2X2's or the non PVC flips. Inside a loose bag the coin can damage them just from movement of the bag. I prefer the 2X2's. The soft plastic flips are know for altering coins. The stiffer ones are better. The soft square tubes also alter the color on BU cents. Again the hard tubes or clear plastic tubes are better. I prefer to buy them online used in larger quantities. I prefer the ones from the 1960's that have the clear plastic lids that lock. But the ones with the white lids are OK also. Check on your collections from time to time to see if they are still safe.

I did some research on the bags I used and are made from poly. NGCS claims poly will not hurt coins, Once I put in bags, they are put in stationary place, never really moved again. I bought 30 100 packs and have a half pack left... PLEASE tell me I safe from corrosion, as I can't phantom switching holders &
