Can anyone help me figure out if this penny has any type of mint error? This coin looks like it has a lamination error on the front with nothing out of the ordnary on the back. I found this coin while searching through rolls of coins from the bank. I read on another website that some coins have scratches on the front because of the crimping machine used to seal rolls. I found this coin in the middle of a roll so I doubt that it is a crimping mistake. Any type of advice on if it is an error or its value would be appreciated very much!! Thanks!!!!
It looks as if a clad dime was stuck to the obverse (possibly in its original bank roll), then soaked for a while in some solution (possibly even water) peeling part of the clad layer off of the dime causing this circular ring around the the lincoln bust. Just my personal thoughts..... Welcome to CoinTalk, -Brian PS: There is no possible way for this to be a lamination since laminations are usually protruding off of the coin or going concave into the coin, this alteration seems to lay flat and evenly on the surface with no elevation what-so-ever.
Also, just because you found it in the middle of a roll, doesn't mean it wasn't on the end of a roll at some point. It's been circulating for 28 years, so it's probably been rolled and re-rolled a number of times. I'd say it's from the crimping; I've seen a lot of coins with that mark. But, that's just my opinion.
I agree... the coin probably got damaged by the crimping machine... this could have exposed some of the zinc under the copper and it could have corroded so that it was not bright shiny zinc looking. Whenever you see damage on a coin in this area it's almost always caused by the crimping.
Not at all possible for it to be a clad dime overstrike. The Lincoln design would have much less detail, and even if it was a dime overstrike, it would remove ALL detail from the Lincoln design to get rid of it.
Roll crimping finger damage. In this case it has scraped all the way through the copper and exposing the zinc.
I think you've misread my previous post. I didnt say that a clad dime was STRUCK on the obverse, I said "a clad dime was STUCK to the obverse". I never thought it was an overstrike. I realize that is completely impossible. -Brian
Why not? I know of no reason why the zinc core couldn't have a lamination. I admit I haven't seen one, but that doesn't mean it can't exist.
As far as I know and was told, laminations are caused by impurities in an alloy ( 2 different metals ) and zincolns are pure zinc with a copper plating. I guess there is a possibility of foreign substances entering the mix...
Impurities can also be dissolved gases, bits of slag, etc. Laminations exist on the pure copper large cents, and I do believe there have been a few seen on the pure silver bullion coins. You don't have to have an alloy to have a lamination. And the zinc core on the cent is not pure zinc it is 99.2% zinc and .8% copper so it is a alloy as well.
Just checked the red book and you are right and the silver eagles actually have the slightest amount of copper in them as well. Wonder how much junk is in the " pure copper " large cents...
