I can't quite figure out if this is a cud or just a damaged coin. There seems to be a blob on the stairs to the right, but I can't get any closer with the cheap microscope. Is this a mini-cud? Thanks for any opinions!
Looks like a hit. Damage IMHO FYI a Cud is a Die Break that is found on the Rim od a coin and extends into the field. Here is an example from my collection
Thanks.. The blob is not added material. It is metal that flowed into the Missing piece from the Die that broke away. That is sometimes what new collectors think when they begin collectiong errors. Same thing for IDB's.. Interior Die Breaks and Die Chips. They are 'Blobs' that form when the metal goes into the missing piece when the blank planchet is struck by the defective die.
You may find that some older books called anything like this a cud. The modern terms define them better.
Not a cud as all cud start on the rim of a coin. The right hand side of the steps took a hit so you’re seeing damage.
Though I agree that FAR the most prevalent chunk-out-of-die (ie: "cud") occurrences are at the EDGE, chunks sometimes fall out of the interior as well. I classify those too as "cuds". See Samples here.
As some others have said, the obverse of the nickel features a "stepped" or multi-level cud that possibly grew over time.
