This is not a cud. I don't even know if it is a die break. This is one reason that I don't like the "so-called" definition of a rim cud, because if we can call a break on the rim a "rim cud", then we should call a break in the field next to the rim a "field cud". To me, both terms are senseless. This anomaly could be a lamination defect. I don't know. Chris
From the photos , I agree it is not a cud and possibly an attached lamination or the result of a damaged worn die .
A lamination can involve the rim too. Laminations are imperfections in the sheet metal so depending on where the blank was cut out of the sheet in relation to the imperfection it can happen ANYWHERE on a coin. All of us with way more knowledge than you are saying it's not a cud. You think we are all wrong?
The evidence you point to is evidence in favor of it being a lamination, not a cud. By definition, one should expect a cud to be sharpest at the rim. On the other hand, laminations - not uncommon with early Wheats - will often have layers of lamination - not one single monolithic piece - and you'll see "sub-laminations" as your arrows point to. And for the displacement to be so notable on the field, we should expect a similar level (or at least close) If I may be frank, I feel from the character of your posting that you're taking offense at differing opinion where maybe none should be felt. As a values judgement (kinda silly as such), there's no "qualitative" difference between a cud and a lamination. On the Internet, we must all be thick-skinned. There are far greater regional and generational differences in form of expression and "acceptable" language than we realize (not even factoring those posting for whom English is a second language), and we really can't use our own frame of reference to evaluate the hearts and intent of others. I was raised a Vermont woodchuck in the 1960's, and now live in a rather hard-edged Philadelphia neighborhood half a century later, and every day I hear language on the streets which would have been fightin' words in my previous days. And so it is on the Internet. Yeah, there are those posting here who just want to get a rise out of you, but not all the words you read which strike you that way are meant that way.
Here is an article from Ken Potter about the definition of a cud. http://koinpro.tripod.com/Articles/WhatIsACud.htm
