This is an uncentered broadstrike.
As several others have stated, this coin shows a fake second strike. The obverse face was struck by a crude counterfeit die while the reverse...
You most likely have a cent struck on a planchet punched out of rolled-thin stock. Such errors can produce cents as light as 1.4 grams. A weight...
This coin is suffering from severe chemical damage.
One form of improper alloy mix error involves an abnormally high fraction of tin and/or zinc. This creates a brassy look and the coins are...
I'm reviving this ancient thread because I wish to retract the thumbs-up I gave the dropped letter on the Polk dollar. I have to drop it back...
All cents from 1962 through the middle of 1982 were struck on planchets composed of 95% copper and 5% zinc. Your coin is perfectly normal. While...
Any reeded coin in which the core is recessed has been altered outside the Mint. While acid can accomplish this, so can machining.
Photos are terrible, but the prescence of an incuse Memorial design on both sides of a previously struck cent makes it virtually certain that this...
This is post-strike damage. The coin was crushed between two plates/objects, one of which had a gap in it. That's why part of the reverse design...
It looks like an authentic, albeit unusual example of incomplete cladding.
Severe die deterioration doesn't have much of a fan base. That said, if it gets truly extreme so that design features are no longer recognizable,...
Looks like silver paint or spotty silver plating. It's not an alloy error and it's not a mint error.
It's machine doubling but it's not without value. When it's this visible it can bring prices above $10.
Despite being slabbed by PCGS this is probably not a mint error. It's far more likely to be a case of post-strike damage or an intentional...
The thinning of the letters indicates this is intentional die abrasion.
It's almost certainly a simulacrum. It's a stain that happens to match the shape of a partial numeral. Notice that much of the rest of your coin...
It's an authentic double clip. Fadeout of the design rim as it approaches each clip is a good sign of authenticity. There's also modest metal...
It's a very nice doubled die.
I see no Blakesley effect at the pole opposite the clip. You'd have to weigh it to be certain this planchet has a curved clip. It's possible...
