These "cracked skull" die cracks are very common throughout the 1950s and do not imply the imminent failure of a die.
Although it could be a strike-through error, I'm suspicious because of the other, smaller indentations scattered around the obverse. So it could...
Looks like machine doubling to me. Both the shield and the date show the same flat, marginal shelving. Since the shield is hubbed in, and the...
The coin was not spooned. It is damaged, though. Coins with this appearance are currently thought to have been trapped in the fins of an...
The same question was posed on the CONECA forum. The consensus was that this was just die deterioration. We could detect no doubled die among...
It's definitely an "acid job". The undersized planchet, perfectly centered design, and uniformly mushy design elements are characteristic of such...
Unfortunately it's a squeeze job or post-strike mint damage. The incuse, mirror-image letters of AMERICA on the obverse and the rim impression on...
It could well be machine doubling.
It's a marginal die break, otherwise known as a "cud".
Looks like a die chip.
Looks like a lamination error to me.
I'm quite confident that this is a lamination error. Sometimes these are called "lamination cracks". The metal is cracking and lifting up,...
Yes, the 1924-S cent shows a case of progressive indirect design transfer.
A flipover double strike would ordinarily show sharper borders along the edge of the six-pointed star (the transferred impression, that is). So...
It's a case of progressive, indirect design transfer -- a form of die deterioration. It's common on very thin coins like silver 3c pieces. It's...
That little metal tag would appear to be a small rim cud. In other words, a small piece broke off the rim gutter of the reverse die.
I agree. Subsurface corrosion.
There's no question that this is an authentic filled die error, a.k.a., struck through grease. They get a lot more severe than this. Some have...
Looks like a minor off-center strike. The rough surface could be from blistered plating.
It's a tilted partial collar. The collar was not fully deployed when the coin was struck. It's worth $2 - $5.
