I've seen many altered coins that look like this. Any time you have a perfectly normal rim on one face, and a flat or beveled rim on the opposite...
The coin is worth face value.
Maybe so, but the heat-treated and chemically-treated nickels I've seen do not closely resemble a genuine copper wash / sintered plating error.
The 195- cent was damaged by a coin-wrapping machine. Looks like the date is 1950
It's a die chip. These tend to develop in the curl of 9's and 6's and the top of 5's. They're exceedingly common.
There are a lot of nicknames, but only three "types" of die error that I'm aware of: die polishing, die chips, and die gouges.
It's an example of "sintered plating" or "copper wash". An unintended, thin layer of copper was deposited on the planchet prior to the strike....
A weak strike will not produce this effect. Low relief areas are the last to be affected by a weak strike. The detached leg is apparently due to...
The coins you saw may have been encapsulated by low-budget slabbers. If they used the term "double die", that's a dead giveaway they don't know...
This appears to be machine doubling, a.k.a. "mechanical doubling", "machine damage doubling", "machine doubling damage", "strike doubling",...
It is not possible to securely identify a coin struck on a blank ("Type I planchet") if that coin is struck fully within the collar.
This appears to be die deterioration doubling. The late die state would be consistent with this diagnosis.
I think earlier I mentioned a ballpark figure of $1000. I might hedge at this point and guesstimate somewhere between $700 and $1000.
I'm not a dealer. So any pricing info I provide should be corroborated with a second and third opinion. Your elliptical clip cent is probably...
I'll try to dig one out. In the meantime, weigh your coin. An alteration of this kind often removes enough metal to drop the weight below the...
This does not appear to be a "grease strike", a.k.a. filled die error. It does not appear to be an error at all. I say this because the area...
It could be a filled die error, but this would be an unusual location and unusually localized for such an error. It could be a die abrasion ("die...
To paraphrase Donald Rumsfeld, we use the terminology we have, not necessarily the terminology we'd like. All standard references, and all of...
This is not a cud. A cud is a die break that involves the rim. It may be an interior die break, but I doubt it. From the looks of it, it may be...
Sounds like finning to me. It's caused by abnormally high overall striking pressure, or a slight bit of die tilt that increases localized...
Separate names with a comma.
