It is probably an improper annealing error. Previously called "copper wash" and "sintered plating" errors, a thin layer of copper ends up at the...
It looks like die deterioration doubling to me.
It's die deterioration doubling.
It was struck several times by fake dies.
It looks like a die gouge or a linear die dent.
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.
Separate names with a comma.
