This is not machine doubling. It is an incuse form of die deterioration doubling. For some reason it pops up with unusual frequency among state...
As several others have remarked, this is a "die attrition error". At one time the die was misaligned toward the right and smacked repeatedly...
What you have is a bi-level die crack. Instead of being characterized by lateral spread (which produces a raised line), you instead have slight...
As most have said, it's an old squeeze job.
Rascal is correct. The "wire" appears simply to be a little bit of metal shaved off the "slide zone" during the second strike by the edge of the...
Relative to other striking errors, they're fairly common. Small indents like this have little market value, maybe a buck or two.
It's not a dryer coin. Someone ground off the obverse perimeter.
The dime has a small indent. An overlying planchet was struck into it.
I agree with the majority opinion which interprets this as an in-collar double strike. Nice find.
A die cap can come loose and rotate. Or it can come loose and shift to one side. Or it can do both simultaneously. Shifted cap strikes are much...
It was struck once through a rotated, late-stage die cap. This produces a set of normally-oriented, incuse design elements.
As others have indicated, this is an example of die deterioration.
It's some form of post-strike damage. The reverse face is in horrid condition, and I expect this is from the same forces that generated the...
I'm not sure what you're referring to. The proto-rim should be flattened where the other cent overlaps it. This would be true regardless of...
To me it looks like the impression of the design rim has invaded the slide zone. That's not unexpected since the design rim is higher than...
I agree with you, Matt. This looks like an "enhanced error". Someone took an ordinary off-center strike and pressed the obverse design of...
A featureless, often puckered area is always present opposite a large cud. That's for two reasons; 1) A lack of resistance to the impact of the...
Probably between $30 and $50.
It's a multi-level cud. The shape of the fracture zone can vary enormously from vertical, to sloping, to stepped. Yours falls into the last...
It's a case of overzealous intentional die abrasion. 1972-D and 1974-D cents are notorious for this.
