I just found this in my stash. A rim to rim lamination taking in the word TRUST. I don't see it in the Pre Cud listings.
A Lamination is a Planchet Flaw so it falls under the Planchet Error Category. A Cud is formed because of a Huge Die Break so that would be a Die Issue and the Die Error Category. Laminations are unique on each coin. They don't form into Cuds.
