Hi, I'm Greg and I am an independant coin grader aspiring to work for PCGS. Background in insurance. I joined this group simply to reply to a user who claims to be a national coin dealer, who, if truly a coin dealer, has steered a cointalk member COMPELTELY WRONG! I mean no offense to this coin dealer. But if the picture posted is the coin truly held by the person who posted it, it clearly shows all of the features of a REAL DDO 1955, not a "Poor man's double die" which in reality is NOT a DD. The doubling that appears on the last digit (5) of the date was caused by die deterioration. Overused dies begin to errode and this produces the effect called "Die Deterioration Doubling". Its very common, and the same effect is found on the 1953 penny.ast 5 of the date was caused by die deterioration. When die are overused, they begin erode. This is called Die Deterioration Doubling. Not only is this very common, but this same type of effect can be seen on other dates like 1953.
