As I've said before, I'm defining Flaws as accidents that affect individual coins, and Errors as things which affect the process, producing lots of identical coins as a result.
By this definition, a crack is an error, but a strikethrough is a flaw, for example.
But where does doubling fit in? Die doubling is clear, but pretty much unheard of here, at least in decimals. But mechanical doubling, which may result from a loose or improperly tensioned die... well, I don't know.
Lots of people seem to class doubling as PMD, on the basis that it occurs milliseconds after the die hits. I think that's completely wrong. But is it an error, as many thousands may be made before the problem is corrected? Or is it a flaw, since strictly speaking there's nothing wrong with the dies, and once settings are adjusted, perfect coins will again result?
What do you guys think?
I doubt the doubling would be exactly the same each strike. I would say its an error.
Who cares, something obviously "wrong" is a keeper. That's all there is to it me thinks.
I thought that to until I ended up with hundreds of dollar that are still only worth hundreds of dollars so I can't see it's worth the trouble as no one want them unless they're the big one's..very much like polly notes, no one wants them unless it's a huge error or very rare and MUST be in UNC so this makes it very hard so we hoard for our selves because we like it :(
