It looks like an authentic error to me. The weakly-struck areas on both faces are signs of authenticity, and effects often seen in missing clad...
I agree that the second strike was delivered by a pair of fake dies. The soft, blended overlap is characteristic of such fakes. A genuine...
The "bubbles" might instead be a series of die dents. At any rate, the pattern of exposure of the zinc around the periphery of the coin is...
Without a photo or a more detailed description, it's impossible to diagnose this error or even determine its authenticity. If its diameter is...
The broadstruck half dollar with clip is absolutely genuine. I'd guess its value at somewhere between $100 and $150. A curved clip will...
Chris' study is far from conclusive. The jury is still out on the nature and origin of the "extra leaves". Unless you tuned me out completely,...
Damage from a coin-wrapping machine.
I agree with Conder101.
It looks bogus to me. I don't see any of the diagnostics. There's no metal flow in design elements bordering the straight edge, there's no taper...
Mike Diamond and James Wiles anchor the error and variety sections, respectively. It should prove to be a useful addition to the forums that...
An unusually strong example of machine doubling.
The mintmark has been part of the master die since 1990. So it's theoretically possible for a doubled die to occur on the mintmark subsequent to...
Extreme cases of strike doubling (machine doubling) are quite desirable and can fetch prices of over $100. I'm talking about the production of...
If the bright-looking areas are silver-colored, then it's probably a failed attempt at plating.
ANACS is correct. It was struck through a late stage die cap. It's not a brockage, since a brockage requires the presence of incuse,...
Fake. A double squeeze job. Painful lesson for the buyer.
Sqeeze job, vise job, hammer job, sandwich job -- whatever you call it, it's vandalism.
Copper-plated zinc cents are not annealed. This is a case of blistered plating. Heat generated by the strike causes gas to expand between the...
The initials are raised on the die and incuse in the coin. Intentional die abrasion ("die polishing") will remove the initials before anything else.
Yes. It's a light die clash.
Separate names with a comma.
