Dear @Scuba4fun777, Rheingold, asked: "Could this be a planchet flaw as well?" Unfortunately, my way of posting confused you because in addition to using a different color for my initial reply I FORGOT TO ADD QUOTATION MARKS for Rheingold's additional comments. My original post should have looked like this: Rheingold, asked: "Could this be a planchet flaw as well?" Yes. A lamination is usually caused by a flaw in the planchet. "As far as I know a coin with lamination error cannot be encapsulated from a TPG. A coin with a planchet flaw otherwise can." it's best to check your "AFAIK" opinions before posting. At least two TPGS slab laminations. Someone else can check on the other two. It appears to me that the long chunk on the neck has become partly detached (from the dark area to the left) and is pushed over on to the neck. It is not a strike thru. Thanks for pointing out my errors! PS I'll repeat what I posted to be more clear: A long chunk of the coin's surface on the neck has become partly detached and is pushed over on to the neck. It is not a strike thru.
