In March 2007, Rasputin41 posted images of a 1983 cent with an unusual brockage of Lincoln's bust on the reverse face. I would like to use them...
Mike Diamond, here. I helped you in figuring out your 1983 cent with the unusual brockage of Lincoln's bust on the reverse face. I'd like to use...
The British coin does show severe machine doubling (push doubling subtype).
A combination of chemical and mechanical damage. The plating was chemically stripped and the coin was apparently circumferentially compressed in...
I agree that this is a struck-through error.
I don't drink coffee. Maybe I should start. :)
I just wanted to alert you to some mistakes I made in recent Collector's Clearinghouse columns: In the column on guided die scratches, I was...
A late-stage brockage. This is one of many types of capped die strikes.
Assuming it is underweight, then the coin was most likely struck on a planchet punched out of rolled-thin zinc stock. Among zinc cents, such...
The article that features the brockage from the folded die cap can now be seen in the latest issue of Coin World. I've sent you a copy, Jeff.
The appearance of the lead-off nickel is indistinguishable from an improperly annealed planchet.
The terms "sintered planchet" and "copper wash" refer to theories that were debunked years ago. The currently preferred term is "improperly...
It was double-struck and then cancelled. As with many such cancellation strikes, the coin lay between a cancellation die and a second coin, which...
This is clearly post-strike damage as the reverse is damaged along a similar arc.
Although I failed to win the coin in your eBay auction, I would like permission to use your photos in an upcoming Coin World column. Thanks. --...
Yes, the cancellation strike is clearly seen on the second picture. Cancellation strikes ordinarily reduce a coin's value, so if this strike...
The raised design of a cancellation die is readily seen on the reverse face. Many recent Egyptian errors show cancellation strikes.
Certainly, if a coin is struck out of collar and shows both designs offset to the same degree and in the same direction, then it's obvious you're...
Contra Conder 101, a misaligned die error is not dependent on the presence of a fully or partly deployed collar. A misalignment can occur in...
The obverse face is not misaligned. It just shows slight finning of the rim. The reverse face is not misaligned enough to be considered an error.
Separate names with a comma.
