The mint started plating zinc core planchets in 1982 with copper. What you have are coins that were plated after market and the plating is wearing off. They are now considered damaged coins. Not worth the time or effort to try to remove it as they would still only be worth 1 cent each.

It appears that it has a coating of something someone has added to the coin after the mint which is flaking off.

I'm wondering if anyone else has had coin plating come off from being in extreme heat them n cold (barn attic) over years? I find it difficult to believe from the coins found in the boxes that they were all 'plated'by someone after. Anyways I still appreciate the comments (under the grading section ') Here's a couple others.

Plating is easily and cheaply done by 'many o high school chemistry classes, and the fact that you found a jewelry box full says someone was planning to make jewelry out of our of them. Very common occurrence.

Electro plating with zinc is easy enough to do in a high school lab experiment.
However, it this case, the zinc core is showing through in the gash in Abe's shoulder. I notice that 'IN GOD' is fainter than 'WE TRUST". Copper plating in patches is gone, for whatever reason, but if heat was responsible, the coin would be blackened.
Anything can be assessed for condition but that is rather beside the point with the reasonable quality of pictures provided. Value one Cent, unfortunately.

Not all the coins are plated. The example of CAN 1960 is not plated coin so will not peel on the differences of the temperature or humidity. The first coin was plated after strike and they do a very poor job.

Almost looks like paint to me. If not paint it is plated. U.S. cents are copper plated starting in 1982. Zinc plated was only in 1943. John1

It doesn't really matter if they were painted or coated. The fact that it was done after they left the mint makes them PMD and only worth face value.
