Definitely post-strike damage.
There seems to be a pressure ridge at the upper margin of the upper limb of the indentation. If so, this would also indicate post-strike damage.
Sounds like you've got an "acid job". The cent was dipped in acid or some other corrosive liquid. A complete, but uniformly fuzzy design is...
It looks like post-strike damage. If the surface of the coin curves downward toward the indentation, then it is assuredly post-strike damage.
It's a peculiar form of die deterioration doubling associated with copper-plated zinc cents.
And a quarter missing a clad layer should weigh around 4.67 grams.
It could be severe die deterioration.
This by far the most common date for nickels struck on cent planchets. It's probably worth around $200 - $250 in BU condition.
Definitely not a die crack. It's probably a die gouge, although you can't rule out a linear blister in the copper plating.
I still prefer "clip" over "incomplete planchet". The latter term is unwieldy. How would you describe an incomplete clip? An incomplete...
I can see now that the curvature is normal. It's definitely an authentic curved clip.
Damaged outside the Mint.
I'm not sure. It doesn't look curved enough for a curved clip, but it is concave. Things to look for include: 1) metal flow in design elements...
It looks more like a strike-through error to me.
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...
Separate names with a comma.
