This is suppose to be a FUN and hopefully educational post. But, there is a curve ball in the post and you'll understand what I'm up to and why when all the answers are in. I'm posting a 25X image of something commonly seen on coins. It is on the bunch of leaves and continues into the field. What do you call it: The "trick" is to be specific.
You have 5 knowledgeable responders, with 5 reasonable (different!) answers. I hope you're having fun!
Just be a little bit more specific...Maybe call it "A minutely, slightly partially detached small piece of a somewhat delaminated flake of a very much defective planchet."
Problem is, if you submitted this to a TPG it is too minor to even be designated as an error. So, technically yes, but practically no.
I posted this on another forum and it caused quite a stir about the correct terminology. First, minor error or not, at least one maj0or TPGS would mention this on the label because if some folks received a coin with a ripped up surface and missing design they would not like it! Others would be glad to "cherry" this minor error if not mentioned on the label. Second, this is a lamination. Part of the surface is ripped up with cracks across both sides in the leaves. The "trick" part is the fact that part of the lamination is missing. It has become detached and is no longer on the coin. The dull hole in the field is where it was and the part that was covered by the original split. Most numismatists call the missing area a "detached" lamination. This image shows both detached and attached. "Partially Detached Lamination" works for me. I don't use the word "delaminated" as the metal of the coin is homogeneous and not layered (laminated) as a clad coin would be.
