I have unexpectedly come into possession of...
I may have paid too much
An acid-treated (to remove the copper) coin will have either tiny bits of copper left in the protected corners or will have thinner devices because the acid eats some of the zinc after the copper is gone.
See how thin the letters are on @Heavymetal 's coin. I'm calling that acid...
At least give him back one of the Ls - ZLincoln
It was part of a mixed lot of coins which had some coins I was interested in. The lot wasn't itemized, and, looking at the picture, I was wondering what the 1995-d coin was - that part of the pic wasn't very clear.
Sadly, the cover of the air-tite was off when I took the pics. (As soon as I got it I put it in the air-tite because I know how badly zinc oxidizes) I am working through the "new-guy-learning-to-take-decent-pictures" thing.
Anything help with those spots? I've put it in an air-tite to minimize further damage. (It was in a clear flip before.)
Well, then maybe this really IS a mint error. It looks normal, no eaten up spots, no bits of copper that I can see. It looks better in hand than in these pics.
Perhaps the hammer caused the bottom of “ATES oF” to be flattened at the top of the reverse of the OP’s coin.
That is very commonly seen on Memorial cents and is a striking problem caused by the fact that those letters are opposite the lower part of Lincoln's bust which uses up all the available metal. The metal would rather flow into that big open void in the obv die than into the tight spaces of the lettering on the rev die.
The OP coin has a dead flat surface appearance with no luster. But it isn't dark and rough. I suspect it has been plated post mint and is NOT struck on a non-plated planchet.
Are you suggesting that another layer of zinc was plated on top of the copper plating on top of a zinc planchet? Intriguing! But I finally located my scale and the coin is 2.4g. The same scale shows post 1983 cents as 2.5 g, as expected. So it seems likely that this is just the planchet with nothing plated on top of it.
