The surface is covered with tiny bumps. They are not blisters in the plating. The bumps indicate something was done to the coin outside the Mint....
It's a die crack, not a cud.
If it is copper-plated zinc, then it's still a great error, since it would represent a cent struck on a planchet punched out of rolled-thick zinc...
Balancing the coin on a finger and tapping it with another cent does the trick. A low drop onto a formica kitchen countertop also works. A...
I see nothing in the photo to distinguish this coin from an ordinary, and rather dirty cent. It sounds like you're describing a dent in the coin....
A brockage is an incuse (sunken), mirror-image version of the design created when a previously struck coin is struck into an unstruck planchet or...
That's certainly within the range of copper-alloy cents. You may have a transitional error worth several thousand dollars. Does it have the...
Rasputin41 sent me much better photos of his controversial cent. I am now almost certain it is a genuine, albeit complex, brockage. As best as I...
As a matter of fact, it is wholly unecessary to dip a coin in acetone or any solvent once you're familiar with what a glue job looks like....
Acetone is an organic solvent which has no effect on coin metal. I have used it many times to dissolve glue and other sticky residues without...
It is not an error per se. It is an occasional EFFECT associated with broadstrikes, off-center strikes, multiple strikes and any other sort of...
It's called "starburst". The phenomenon is poorly understood. Explanations offered by the Mint don't hold water. My best guess is that it's due...
This is generally called "split-line doubling". The copper plating simply split as the coin expanded. It's often best seen in association with...
It looks pretty good from where I'm sitting. Look for these signs of authenticity: 1) a weakness of the rim at the pole opposite the clip...
A die gouge often only affects the field. The letters are recessed in the die face and are thus relatively protected from damage. It has all the...
Is this a "reprocessed" (re-plated) cent? If so, this might represent a plating defect. Otherwise, it appears to be a long die gouge. Possible...
I'd be happy to evaluate it for you. You need only include return postage/insurance. I am the President of CONECA, the national organization of...
It's die deterioration doubling. The orange peel texture is also consistent with this interpretation.
While it may be a glue job, there are some indications that it is a genuine brockage. The weight of the coin is normal. Glue would add some...
My verdict is machine doubling. The marginal shelving is characteristic.
Separate names with a comma.
