It's a curved clip. These are sometimes also called "incomplete planchet" errors. I prefer to use the term "clip". Mint employees refer to them...
These are "lamination cracks" and "lamination peels". The metal is flaking and peeling as a result of impurities in the alloy. Quite common and...
All the clips look good to me except the last one (the 1967 cent). The rim on that one is intact but pushed in. That wouldn't occur with a...
It's possible that you have a "brassy plating" error. A brassy color is thought to be caused by a copper plating solution saturated with zinc...
There are at least three things to look for in a genuine clip: 1. A vertical edge that usually shows a "belly line" or "breakaway zone" where...
These are not partial collar errors ("railroad rims"). These are encased cents (lucky token cents) that have been removed from the surrounding...
It is my opinion -- one that is shared by many others -- that strike doubling IS a minting error. After all, it is related to the downstroke of...
It is strike doubling (a.k.a., machine doubling, machine damage doubling, machine doubling damage, mechanical doubling, ejection doubling, etc.)....
Thickening of the letters is most likely due to die deterioration (die wear, die fatigue). It's very common on 2000-P nickels.
It is a common place for die cracks to form.
I concur with DJGSMP and Jason.
Yes. Chemically etched and eroded.
Thanks. I would like to photograph it. Contact me at mdia1@aol.com.
I agree with Speedy. The coin looks highly questionable.
Sounds like an "acid job". The coin was immersed in a corrosive liquid that eroded the surface. Such coins are characterized by: 1) thin or...
Fascinating. This is a bizarre form of die deterioration. I would, in fact, classify it as a "soft die error". This is a rare form of die...
It would most likely be a die crack. It may not show up on the top of the letters because effective striking pressure is lower here, and might...
"Severe" is just a descriptive adjective, not an official designation. "DDD" is all you need.
Severe die deterioration doubling.
It's not a mint error. The obverse was removed by some sort of lathe.
Separate names with a comma.
