Hi, I was digging through pop machine change and found this nickle with a cud under cents, it looks like a ufo, lol! I also found a 2020 quarter with a W mint mark.
Sorry, I forgot to add that both sides are distorted, kinda puffy looking, camera is having a hard time showing what I mean. Maybe grease in die or something. I'll try with a different camera later to see if I can get better image so you will know what I'm seeing. Thanks
Could be an IDB - Interior Die Break Not a Cud.. A Cud involes the Rim and flows into the field. These are Cuds - And the other issue I'm thinking it might be is a strange Lamination. If you look to the left under the letter E you can see an anomaly on the Nickel surface.
Oh, ok, idk then, it is a lump of metal under the word cent. Could it have been like a hole in the die or something? Thanks for the reply though! I'll see if I can get better pics.
@Wadesterling101 Definition: When a thick flake spalls off the interior of the die face it leaves a void we call an interior die break. It appears on the coin as a featureless lump. Unlike a cud, an interior die break has no direct connection to the design rim.
@Wadesterling101 A cud on a coin is a damaged area resembling a blob on the surface of a coin. The cud is raised above the field, and it obliterates the device or inscription where it appears. Cuds are the result of die cracks or die breaks which have become severe. They can also form from die chips where part of the die surface has become damaged and broken away.
Just a guess, if it were my coin, I would think that the puffyness on the reverse looks to mirror the shape of Jefferson's head, upside down, resulting from a die clash, and possibly causing a chipped die at the C. Also, could the mark above the T in States have been made by a piece of the chip?
@Wadesterling101 The "puffy" appearance may be what is called "Ghosting" or Progressive Indirect Design Transfer. See info below. Progressive Indirect Design Transfer (error-ref.com)
Appears to me to be a blob of something on the coin, not a die chip. I would try to soak it in acetone over night and then use a tooth pick to try and remove the object. Whatever it is, it is on top of the devices, not under any of them. The "puffiness" might be from having been subjected to high heat. Just a guess. No matter what, NAV in my opinion.
Can't say for sure but it looks like you also have a lamination issue. It appears that some of the metal folded over. The outline seems to match. Maybe prior to being struck.
