When they issued green plates it was all the numbers on the left and all the letters on the right separated by a dot in the middle. After using all those combinations they switched to multiple other formats. Q could be mistaken for a 0 and I can be mistaken for a 1, so they aren’t used on formats when the letters and numbers aren’t as easily divided. O is also not used for this reason.
