The average coin dealer knows next to nothing about errors, and therefore, any opinions issuing from such a source are to be disregarded. If the...
The color of the suspected missing clad Sac is pretty convincing. The design is crisp, which would seem to rule out a clad layer removed by acid....
Now, that's very interesting. There is now a chance that you've got a rare and very valuable "transitional error". Since weight, diameter, and...
The coin was vandalized. The puffy, expanded design elements are clear evidence of this. No striking error would, or could, produce this appearance.
Looks like a die gouge to me.
The silver-colored Sac dollar is probably plated, unless you can see the copper core on the edge. If you can see the copper core, then it might...
As far as the back leg goes, this would appear to be a case of intentional die abrasion ("die polishing"). Low-lying areas of the design are the...
This is post-strike damage. I've seen it many times before. Exactly what causes it, I do not know. The design features are pounded into mush....
The effect you're seeing is pretty common on off-center cents. Zinc exposure would be due to at least two factors: 1) Thinner-than-normal...
This is post-strike damage. The "partial collar" is adjacent to the obverse face, rather than the reverse face. This is impossible in a 1988...
I agree that it's not a genuine error. The pitted surface, the somewhat soft outlines of the design elements that are present, and the lack of an...
Like I say, it was probably either plated or the Cu-Ni clad metal was smeared onto the edge during blanking as the result of a dull blanking die...
I know most people frown upon invasive tests, but I prefer certainty over uncertainty. The mark will be invisible face-on, and nearly invisible...
Since all other specs are the same as a normal quarter, the liklihood is that the edge was plated or the Cu-Ni clad metal was smeared onto the...
It could be either mechanical doubling, die deterioration doubling, or a combination of the two.
They usually sell for between $15 and $35 on eBay.
This is a capped die strike. The coin was struck through a late-stage obverse die cap. Nice find.
