It's most likely a form of machine doubling known as "slide doubling".
Yes, you typically find this kind of damage on broadstruck and off-center coins.
The ridges on the edge of this double-struck cent represent post-strike damage. Depending on which source you consult, it's produced either by a...
Struck through grease.
Tommy_cent sent me some better photos. Since the area to left of the D fails to show the E of cent, and since this area is part of the same...
There's no "partial reverse", just the typical appearance of a full uniface broadstrike.
When it last appeared on eBay (around 2000), the asking price for the cent on nickel planchet was $1500. It did not sell
The thing is, a dropped letter -- especially one positioned on the opposite face -- should not occupy the same position as its normal raised...
I strongly suspect that the D on the 1964 cent is a contact mark from another cent. It's very rare for a dropped letter to appear on the face...
The coins are perfectly postioned because that is what a chain strike produces 100% of the time. It cannot be any other way. The apposed edges...
This is mated pair consisting of two chain-struck cents. There's no reason to think these had any help as chain strikes are pretty common...
The 1981 cent on nickel planchet is a genuine error, although it almost certainly had some assistance. There are also several Susan B. Anthony...
They're not as rare as you'd think. They pop on on eBay pretty often. They're much more common than full-thickness, in-collar uniface strikes.
This is an in-collar uniface strike (full indent) on a split or rolled-thin planchet.
The rim is pitted, just like the rest of the coin.
The soft, blended overlap of first- and second-strike elements is diagnostic of fake second strikes delivered by a soft die. These are very...
Fake one-sided double strike.
Acid damage, without a doubt. Same for the second coin.
It could also be a cent struck through a lamination flake that detached from another planchet. The absence of any surrounding lamination cracks...
It's a die chip. The term "die break" is non-specific and refers to any form of brittle failure that leaves a void in the die face. A cud is a...
Separate names with a comma.
