The design rim is extremely narrow in 1982 quarters. Even a very slight misalignment will put the date right at the edge of the coin. This...
The reverse face was removed by a lathe or milling machine.
Both defects are the result of post-strike damage/alteration. The upper one appears to be solder, while the lower one may be metal that was...
It's in such bad shape that there's no way to tell whether it started out as an authentic error or as a coin that was trimmed outside the mint.
It looks like a planchet flaw, possibly pre-strike damage that wasn't erased by the strike. The fact that the crease passes beneath the R of...
Post-strike chemical damage.

This is not an error at all. It is a "lucky token" cent (encased cent). It used to reside within a ring of metal (often aluminum) with an...
These are sometimes also called "forced broadstrikes". Sometimes a planchet is surrounded by a partially deployed collar. As the planchet...
The word "IN" appears to be flattened in the affected area. The reverse rim directly across from it may also show flattening, but I can't be...
Post-strike damage, in my opinion.
All of the major grading services are reasonably competent when dealing with simple errors. They do not do a good job with novel, subtle,...
Post-strike damage, without a doubt.
It may be glue. Or it may be an area etched by contact with corrosive substance. It's not an error.
