What should I look for on 1959 DDO cents? keep in mind the master hub was continuing to swell at this time and was replaced in 1969 because the devices were enlarging on the designs. so on this 1959 there were doubled dies, but certain areas were noticed more than others. so there is what to look for on the spread. (something always to consider on a doubled die)
