Here is a 1973 Canadian 10 cents and it appears to have doubling on most of the letters on obv. Is this just die deterioration doubling or something else. On the second E of Elizabeth it looks like seperation. Look at the tops of the letters. Ok, I am seeing notching on the first E now and seperation lines on the others, maybe this is a double die? The second picture has notching in the E, the 3rd and 4th and 5th pics have seperation lines.:hammer: Even though there is notching on the E, this must be die deterioration doubling. It looks very similar to these pictures: http://www.geocities.com/NCADD/educational3.html - die deterioration dblg. on tops of letters. If it were die doubling the doubling would be to the side of the letters not above.
Lucky, The doubling appears flat and more like Machine Doubling (Strike Doubling as some call it)! Also, there is actually a form (type or Class) of Doubled Die doubling that exhibits itself on the coin as doubling towards the rim or towards the center of the coin. This form of Doubled Die doubling is Class II and is called "Distorted Hub Doubling". For more information on the types (Classes) of Doubled Die doubling, go to the link below. http://www.coin-gallery.com/cgstanton3.htm Frank
If it were class II Double Die, then it seems that we would see a secondary image at the bottom of the letters also. But I'm not seeing any secondary images execpt in the A, L, and Z. My pictures are not real clear up close. Maybe if I had an SLR Camera we could tell more. I see a slight secondary image in the A, L, and Z of Elizabeth II. All of the other doubling is at the tops only, so maybe die deterioration doubling(a form of strike doubling)is my bet.?.?.?. Description: It appears as protruding metal on the doubling at the tops of the letters with seperation lines and maybe notching on the E. Slight secondary images are seen in the A, L, and Z in the middle and lower portions of the body by me.
