Recently got about 200 blazing red coins from 1953 through 71, MS60-65. In this lot were 4 1955d, a 1957d and 2 1958 with die cracks across the forehead. The 57d is just like the 55d, the 58's are bit different. I call them my Booth pennies. Haven't seen much info on this variety. Would the mint use the same die from one year to another if it had a crack? Was there an issue with late 50's dies?
