The spread is too great for machine doubling and the sharp, intermittent penetration of first-strike details through the second strike is fully...
This would appear to be an in-collar double strike.
Another unlikely circumstance is the perfect alignment of your coin and the obstructing matter that covered it on the obverse face. Neither was...
It's certainly true that a perfect alignment can occur, but the chance is 1 in 360. Combine that with the smaller-than-expected expansion, the...
The "color change" appears to be crud stuck to the surface. Copper plating is not "pulled away" from the surface of a zinc cent. It splits due...
Existing terminology and definitions leave much to be desired. But we're stuck with it, so we might as well apply them as originally intended.
This all appears to be post-strike damage.
SuperDave, "cud" and "rim cud" are not the same. A cud or corner die break involves the rim gutter and at least a little bit of the adjacent...
If you PM me, I'll give you my mailing address.
These cracks are too small to determine if they propagate primarily in the horizontal or vertical plane. All one can say is that the planchet was...
I can't tell from the photos if the row of U-shaped defects represents post-strike damage or damage to the die. If the latter, it could be damage...
I only see evidence of die deterioration. I've never heard the term "pull-away" and it describes a process that, as far as I know, is imaginary.
Unfortunately, ANACS slabbed what is most likely fake -- a squeeze job. A normal cent was placed between a struck cent on the reverse and some...
The clad layer split internally along the horizontal plane, folded over, and was struck into the coin. The clad material fell out after the...
Glue.
This appears to be die damage.
The radial or pinwheel scratches indicate that the obverse was machined. I don't know what kind of device creates this pattern, but I see it all...
Herbert's terminology is a mess. Many "major die breaks" are trivial in size. He never defines, nor even mentions, what a "minor die break"...
Incorrect, kanga. A "rim cud" is a die break that carries away part of the die's rim gutter and nothing else. A cud proper involved the rim...
It could be a rim cud in which one end of the break isn't recognizable because of slight die tilt. Notice that only the upper left quadrant has a...
Separate names with a comma.
