The reverse was buffed in a radial fashion. The peripheral lettering was distorted as metal between and lateral to the letters was eroded. This...
I see no clash of any kind on the left-hand coin.
The reverse was mechanically altered outside the Mint. It's not an error.

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....
Separate names with a comma.
