I found a Lincoln cent in a roll it is real beat up but thing I noticed it is not flat. I think it may been heated up and warped.What do you think?
I think it's just some kind of damage from being in circulation. By the way, the US Mint mints Lincoln cents, not Lincoln pennies. Welcome to CT!
Hmmm - just a guess, but I'm gonna guess somebody stuck it in a fuse box, not realizing it wasn't all copper. edit - well, as soon as I posted mine yours showed up. Seems we think alike
Do you mean that it is thinner on one edge and thicker on the other? Could just be a tapered planchet. When blanks are being cut out of the strips of metal sometimes the strip is thinner at the very end causing a tapered blank. Minor error.
No he means that the surface is concave. Exactly like it would be if stuck in a fuse box and the the fuse screwed back in. And if you're not old enough, you probably don't know what I'm talking about.
It is concave it does not lay flat the center of the Lincoln side is pushed out and the back side pushed in. I see no press marks on it. The Lincoln side does look like it might have been heated up.
I thought the fuse screwed in always left a mark on the Lincoln from the bottom of the fuse. But it has been a long time since I have seen one.
A penny (sometimes two) was a quick fix if you didn't have an extra fuse. Not real safe but it was better than not having power.
Doing the "Gold Penny" experiment which gives us so many posts here on CoinTalk, the pennies (cents) are coated with a thin layer of zinc and then heated to create a thin brass skin. The older way was to take the zinc coated cents and hold them in a Bunsen burner flame with forceps or tongs until they turned "golden". When students used the Zincolns for this, they often melted and looked like the OP coin.
