Definitely post-strike damage to the "9". Observe how the metal has been pushed up into a "cowlick" extending from the top of the loop.
Damage from a coin-wrapping machine.
Vandalized with some sort of grinding tool.
Most unplated planchets (and unplated cents) weigh between 2.42 and 2.48 grams, with the average around 2.45 grams. So although 2.51 might not...
Upon examination the coin turned out to be fake. It's plated, probably "wash plated". A normal cent was immersed in a solution saturated with...
Missing initials are either due to a filled die or overzealous intentional die abrasion.
Split dies are always in high demand, because they're rare and dramatic-looking.
Split dies are quite rare, far rarer than typical die breaks (i.e., "cuds").
It's an asymmetrical split die straddled by a retained interior die break and several die chips. I have a dime struck by this die pair. A very...
It's not an error. It's a popped blister. A blister pushed up by subsurface corrosion. Eventually the blister ruptured.
Mainly die chips straddling narrow die cracks. FYI, letters and numbers were not "engraved into the die". They are hubbed, just like the rest of...
Probably struck through grease.
There are only two quarters known that are missing the clad layer on both faces. One is broadstruck and uniface, the other weakly struck as the...
I've seen them sell for this much on eBay. However, the price is variable.
It is a case of die clash, probably enhanced by surface film transfer between the reverse die and the obverse die. You overpaid, though. Such an...
It's a "cracked skull" cent. For some reason, cents from the late 1950's develop die cracks, die chips, and the occasional retained interior die...
I would agree with those who've concluded it's some form of post-strike damage. The edge does not show a partial collar because reeding is...
As Pyrbob said, it's a case of die deterioration.
A minor misaligned die. It has no market value.
It's a die crack, not a die break. By the way, the term "die break" is non-specific. It refers to any brittle fracture that leaves a void in the...
Separate names with a comma.
