Kurt, and arthene, I have some info that may, (or may not, depending on the condition of the coin in hand), be helpful in determining the bead size.. The "N" in Regina is wider than three beads, IF it is small beads. If large beads, then the "N" is NOT as wide as the three large beads. I have a 1965 PL, in cellophane in hand, and sought out the means to verify the size of the beads. I hope this will clear up tose "borderline" cases.
