The reverse was mechanically altered outside the Mint. It's not an error.
I would call it a "ragged notch", but it arises in the same manner as a ragged clip, ragged perforation, and ragged fissure.
I can't tell from the photos if there's a pressure ridge or displaced metal on the right side of the recess. If there is no pressure ridge or...
I am skeptical that this is a genuine ragged perforation ("blowhole"). On the reverse, the edges of the hole are too clean and the corners too...
In a broadstrike, all design elements are present on both faces. In order to diagnose an off-center strike, the design has to be cut off along...
Both off-center strikes and broadstrikes lack reeding. They are both struck "out-of-collar".
It's an off-center strike, not a broadstrike. The design is cut off at the edge on both faces.
A retained interior die break is essentially a circular bi-level die crack that isolates an island of metal on the die face.
There are several possible diagnoses: (1) a 90% "indent" (indentation from an unstruck planchet); (2) struck through a partial (off-center)...
The off-center strike on the Phillipines 50c coin looks like it was struck by two reverse dies, one with denticles and one without. In other...
This is not a partial collar error or any other kind of error. This is post-strike damage. By 2005, virtually all business strikes were struck...
Push doubling is a subtype of machine doubling. Slide doubling is another. The rarest is rim-restricted design duplication.
I don't know. The problem is that, unless a cent is struck out-of-collar, it's impossible to establish the proximate cause of the excess weight....
Since it's isolated in the field, it's unlikely to be a die chip. It could be a die dent or a "bleb" (die erosion pit).
This "rash" is most likely the result of die deterioration as I have seen other, similarly affected nickels.
As some others have said, the obverse of the nickel features a "stepped" or multi-level cud that possibly grew over time.
This cent was either stuck on a planchet derived from rolled-thick zinc stock or struck on a planchet that received an unusually thick coating of...
The puffy, indistinct letters and numbers are the result of die deterioration.
This is die scrape from a feeder/ejector. It's width, sharpness, direction, and the fact that it is restricted to the field proves this to be the...
Definitely a "squeeze job" (vise job, hammer job, garage job, smash job, etc.).
Separate names with a comma.
