Interesting effect. The letter B is smeared north-to-south and south-to-north. This may be true of the E as well, although the primary direction...
Thanks. I've sent you an e-mail.
It was struck through a detached clad layer.
This is an intentional alteration -- a "Texas cent". For some reason, these usually have the copper plating stripped off.
That's up to BJ Neff. He's the gatekeeper of the site.
A clash followed by overzealous intentional die abrasion, the combination of the two wreaking havoc on Kennedy's nose. The coin received a...
The grit could scratch the die, independent of the feeder (or ejector or whatever moving part is involved). It would not produce an interior die...
It's hard to determine the direction of a struck-through progression. It requires the presence of a growing set of die markers.
What you have is a combination of die scrapes and a (largely) field-restricted struck-through error. A gritty paste was stuck to a feeder (or...
If it's solid, then it would most likely be a die dent.
It appears to be an occluded gas bubble. The soft borders would be consistent with that diagnosis. It's definitely not a die break and the soft...
Setting aside the damage, this nickel appears to have been struck through a late-stage die cap. Either that, or the die was very worn. The image...
It's a form of pre-strike damage most closely related to a rim burr.
I've presented photos of these bullseye plating patterns in at least two of my Coin World columns.
Yes, collar clash.
I believe this is a genuine error. I have seen "bullseye" patterns of incomplete plating on other coins. In some, it seems to have been...
No, the split plating does not lift up. However, both phenomena are associated with the areas where tensile stresses tend to concentrate.
I must emphasize that nothing is lifting up the plating from the outside. It has simply lost its bond to the zinc core. It's possible that...
There is no such phenomenon as "pull away" and I have never used the term. Split plating doubling and plating disturbance doubling can be localized.
It has nothing to do with strike doubling (machine doubling). The increased tensile stresses located at the edge of the design causes the plating...
Separate names with a comma.
