The ones I've seen (a total of four) were altered outside the mint by a process similar to sandblasting.
The first dime was damaged after the strike. The second was intentionally altered.
Die scrapes from a feeder finger.
Most likely an effect of die deterioration.
This question was already answered on another forum. This is a brockage from a struck fragment.
I told jzacknae that it would be worthwhile sending the coin to James Wiles for his evaluation. I think it has promise, but the photo's...
It's almost certainly a case of machine doubling. When MD involves incuse design elements the appearance is rather different than when MD affects...
It's a grease strike. Value would probably be between $20 and $25. And that's only because it's a Union Shield cent.
The weight and diameter don't come close to anything the Mint was producing that year in either the Philadelphia mint or a branch mint. It could...
We need a more precise weight down to the nearest 1/10th of a gram. Right now it's hard to say what it is. Part of the problem is that the coin...
Sounds like it's missing a clad layer. If so, it should weigh about 4.7 grams. Depending on condition, value would range between $150 and $250.
It sure looks like a doubled die to me. I seem to detect some subtle doubling in the letters immediately to the right. And I've seen one other...
The coin was vandalized outside the Mint.
My latest edition is the sixth. It doesn't have the dime photo. The 1965 quarter looks to have a struck-in rim burr, but much of it fell out...
Which edition of Herbert's book is the photo in?
Herbert is wrong in his identification. The dime looks like it has a struck-in rim burr. At any event, it's some form of pre-strike damage....
Thin quarters weighing anywhere between 4.9 and 5.3 grams and carrying the S-mintmark have been reported for several dates in the early 1950's....
"Underweight planchet" or "thin planchet" are non-specific diagnoses that are best avoided unless there truly is uncertainty about the nature and...
There are several different sources for a thin, underweight planchet. The two most common are a rolled-thin planchet and a split-before-strike...
This dime was struck on a planchet punched out of rolled-thin stock. Not a particularly rare error.
Separate names with a comma.
