I've read that one of the differences between the E121andE122 cards is the slightly smaller size of the E122 card. When I measure my E122 cards they all measure approximately 31/4 x 2 inches with the exception of aWally Pipp that is 1/16 in.short in length. Aren't the E121"s also 31/4 x 2? Is it normal to have 1/16 in.variations on length and width of E122's? I want ot makesure that my cards are actually E122's before Isellthem.
