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...
If it is recessed (and that appears to be the case), then it's a strike-through error. A piece of debris was interposed between the obverse die...
I have no doubt that it is a genuine missing clad error.
This is an "encased cent" (lucky token cent). A normal cent was squeezed to a smaller diameter as a surrounding ring was struck. The pushed-in...
It doesn't look like an error or variety to me. Most likely post-strike damage, although only a close examination can establish that for sure.
Sounds like your coin is missing one of the outer clad layers. Not a particularly rare error, but it's very unusual to find one in pocket change.
It's a fake.
Lamination errors carry little value, especially in a circulated specimen. If you got 25c for it, you'd be doing well. The undersized coin looks...
Is reeding present? If not, then the coin was altered outside the mint. If it is present, then this may be a case of finning of the rim. Under...
I would think it's just contact damage that occurred after the strike. These appear to be reeding impressions, perhaps impressed at a shallow angle.
All dimes have "raised edges", a.k.a. design rims. What distinguishes yours? Unstruck dime planchets are worth a few dollars, nothing more.
It's worth $400 - $500 in today's market. The planchet was probably intended for a Panama 1/10 balboa. These were minted in San Francisco on...
If it's a shadow image, it may be surface film doubling. If the planchet has a molecule-thin coating of oil or other surface contaminant, you can...
Doesn't sound like a minting error.
Severe damage that occurred after the strike. It's not a minting error.
Sounds like a die chip. Very common.
