Very nice. It is a flipover double-strike. I'd say it's worth between $250 and $350 on eBay.
I think it is more likely that the reverse was removed outside the mint by some kind of coarse mechanical scraping action. The striations seem a...
It appears to be either a lamination error or a strike through a delaminated flake. Some metal has peeled up and bent over near the rim. This...
It's a centered double-strike with no movement between strikes. The second strike was out-of-collar (broadstruck). It might be worth $40 - $50.
The rough surface, mushy details, perfectly centered strike, and absence of metal flow in the peripheral letters indicates an altered coin....
These highly reflective cents are common. They're just business strikes on conventional planchets. Proof cent planchets are presumably identical...
Proof planchets have a slightly dimpled surface from the steel pellets they're tumbled with.
Several off-center business strikes on proof planchets are known.
It could be an error. But you need to post a decent photo.
This is a commonly encountered alteration. Although the wire brush scenario has been floated for years, there are never any scratches or...
While it may be a "grease strike" it might just as easily be a failure to strike up properly. This part of the reverse design lies opposite the...
Someone monkeyed with it outside the mint. It's not an error.
Collar clash. The hammer (obverse) die collided with the top of the collar and/or scraped along its working face.
I'd say it'll end up in the $350 range.
I would say it's probably a strike-through error of some kind, but I can't rule out a defective planchet. A close-up look through a microscope...
Agreed. Die deterioration.
Post-strike damage.
Strike doubling, along with a misalignment of the obverse die. Misalignments and strike doubling often go together, since some misalignments are...
It could be a Rockwell test mark. Dies are tested for hardness as part of the quality control process. The marked die is supposed to be...
Both quarters are squeeze jobs. The same individual is also selling a fake double-struck 1999 cent, with the second strike administered by a fake...
