It is a lamination, caused by improper mixing of the metal alloy. The striking of the coin had nothing to do with this, it is just a flaw in the metal itself. Some of the more dramatic examples can have a premium but most do not and in a few cases, the lamination could lower the value because it could be seen as an undesirable flaw.
