I recently attended this Hemingray 121 (almost left it behind i thought it was nothing special until i looked at it closely. I noticed that diagonally above MADE IN THE U.S.A. was an additional MAD were visible after that the rest trailed off in streaks it is very light and is not an embossing error (Right?) so what is it? I remember hearing something about this occurring when the insulator touches another when still hot I was hoping that someone could tell me what i have ( see images) and give me a value thanks Carter
