A double strike, with an indent on the second strike.
There can be no doubt that this is a cud (marginal die break). The design rim is gone. What you're interpeting as the design rim is persistence...
I did not confirm this as a doubled die. I merely indicated that I saw what appears to be microscopic doubling on the back of Lincoln's neck. It...
Rascal is closest to the truth. It's an area where the die sank in slightly. The sunken area is flanked by two thin die cracks.
Denali quarter dies get a lot worse than this: http://demo.coinworldonline.com/articles/die-wear-can-render-coins-letters-illegible-o
The three sets of clash marks are easily seen. But your photos are too blurred to tell if they're associated with a Type 1 counterclash. I...
The additional photos indicate to me that this is metal added to the coin after it left the mint.
This is not intentional die abrasion. This is accidental die abrasion associated with die scrapes. Most likely inflicted by the feeder...
This kind of reminds me of a 2000 cent with a first-strike or early-stage counterbrockage of the obverse design on the obverse face. In that...
You can send the coin to me at no charge for a closer look. Maybe I can figure out what's going on at that point.
You're quite right about IGWT being out of position. I don't have an explanation.
It's not a partial brockage. The brockage is perfectly centered and I'm guessing is perfectly aligned with the raised design on the obverse face....
I am reasonably confident that this is an authentic error. If the incuse image was pressed into the featureless reverse face of a uniface cent by...
You ask a good question. The centralized weakness seen in a hard planchet strike can be very difficult to distinguish from other forms of...
From the looks of it, this may well be a contemporary counterfeit composed of a base metal. Common-date counterfeits occur in many years and...
It appears to be a genuine broken coin. Additional information can be found here:...
Ragged clips can be derived from the untrimmed leading or trailing ends of strip, or they can result from the blanking die slicing through...
If it's not slide doubling then it's metal flow arising for unknown reasons. Slide doubling, or any form of machine doubling for that matter, can...
The number of brockaged coins a die cap can generate varies widely and depends on how long it stays attached to the die face. The minimum number...
It's an early-stage brockage. I'm not sure why the design is so incomplete, but one encounters such an effect fairly often. It's possible that...
