Ok ..so I found this 2008 penny the other day! Poor Abe. Now clue what happened. Both sides. Take a look! any input? Thx Charles
Pick at it with a toothpick is next after that. Of course be careful not to scratch it, you don't want to destroy its numismatic value.
The mint doesn't cast coins with molten metal. They're struck on a press between two dies. I agree with the others, it's some type of substance that has dried on the coin.
I made one of those recently attempting to familiarize my self with toning, pmd, etc...This can be done on an electric stove and only with zinc. you can get the zinc to melt before the copper.
Either some sort of coating... or the coin has had an unfortunate industrial accident with some acid. If this were Gotham, Abe would now have some cool superpowers and he could help Batman in fighting criminals.
Yes, when i tossed one on a red hot electric stove top, and flipped it quick...it looked like that did.
There's a good clue it's glue on the reverse. You can see where the glue has protected the copper plating (it's still bright), but tarnished in other areas--because there's no glue present.
What I'm seeing looks like glue. Even if it was heat related it would have to be something that happened post strike making it Post Strike Damage with no added premium.
when i did my heat testing, there was toning....I cant find pics, so I will have to re do all my tests when I have time. give me 2 weeks
