Rascal's scenario is complete nonsense.
It's a genuine in-collar double strike with significant rotation between strikes.
Every other dual date coin I've seen involved the same mint. A coin can conceivably get left behind in a conveyor, hopper, or tote bin and then...
This does appear to be a counterfeit strike on a nonstandard, white metal planchet. The bumpy surface details, indistinct LIBERTY, broken D of...
This is a well-executed fake, in my opinion. The second strike was delivered by a set of sophisticated counterfeit dies. Two different dates and...
This is not a dryer coin. But part of the edge was mechanically removed after the coin was struck.
It's a copper-plated zinc cent planchet. These weigh 2.5 grams.
It's an authentic example of a nickel struck on a cent planchet. The "reeding" is post-strike damage from the fluted or rifled barrel of a coin...
The coin was struck through a late-stage die cap and also indented by an intrusive planchet that insinuated itself between the die cap and the...
As others have implied, both faces were attacked with a grinder or polishing device. It's not an error.
This coin shows every sign of being an authentic double-denomination error. Given its early date and excellent preservation of the host design,...
A very nice example of a coin struck through die fill ("grease").
If, as I suspect, your coin is normal weight, then it's quite possible that the bottom coin (the brockage-maker) was abormally thin as the result...
An in-collar, first-strike brockage featuring the obverse design on the reverse face is a rare error. It begins when a newly-struck coin remains...
Of course, the term "die adjustment strike" is untenable as it is impossible to determine whether the weakness is due to the coin being an escapee...
It would be considered a "struck-through" error or a "filled die" error.
Although the photos are not ideal, I'm inclined to think that this is a genuine, in-collar, first-strike brockage. The strong finning of the...
There are other die dents -- curved and straight -- that have also produced pressure ridges. They're entirely accidental.
Your memory is faulty. I've never characterized these as die gouges.
It's most likely a cent struck on a planchet punched out of rolled-thin stock.
Separate names with a comma.
