Message:: [QUOTE="Get Real, post: 2526603, member: 81585"]In order to have delamination you first have to have a laminated material which this is not. I think you are misunderstanding the form of the word. To laminate means the layering and bonding of 2 or more materials. Delamination means the separation of those previously layered and bonded materials. Lamination is term used to describe a defect that occurred in the manufacturing process in a solid material that for one of many reasons caused separations to occur in the final product. Wikipedia is a great quick "go to" for some information, however I would never use that for technical arguments. They are just a bunch of "just out of High Schoolers" searching whatever for information they can find on a subject and they also receive input from people just like us that is mostly unconfirmed. They should never be considered to be the "Authority" on anything. The proper term for this in metallurgy is: (Spalling - Buckling or flaking off of the surface material.) which is usually caused by: (Inclusions - Nonmetallic materials in a metal matrix. Sources include reoxidation, refractories, slag, and deoxidization products.) or by: (Impurities - An element unintentionally allowed in a metal or alloy. Some impurities have little effect on properties; others will grossly damage the alloy.) other causes can be improperly mixed metal alloy matrixes. A "Laminate" is a material manufactured in layers. In metallurgy the term used wouldn't be either, the actual term is called "Clad" or "Cladding". clad (klæd) v. clad, clad•ding, adj. v.t. 1. to bond a metal to (another metal), esp. to provide with a protective coat. adj. 2. bonded with a protective metallic coat: copper-clad cookware. Typically the terms "Laminate" or "Lamination" would be used in other industries like Woodworking and technically it is not combining materials, its layering them to achieve greater strength, or a lighter and more cost effective product. In Metallurgy the term "Laminate" is not used and "Lamination" is used as a defect and not an intended outcome. These terms have been used in this industry for many, many, many years which is why its called and "Industry Term" and they are recognized world wide. I seriously doubt that anyone will change them based solely because someone does not agree or accept them. JMHO! Now, About your coin! I personally like it and if it were mine I would be proud to have it in my collection. There are several things that I see on it that people haven't addressed yet and for that reason, at least for now I am going to hold my opinion about what I think actually caused this. I think it is a very interesting piece and I do agree that is a planchet error so in my opinion it should demand a small premium over normal value.[/QUOTE]
