I bought another 1967 GA license plate yesterday to replace the one presently on my car.
I liked the the number on this "new" one better and it's from the county I live in. The first digit on the old GA plates is the county rank by population. Mine is #7.
I guy I know that lives across town has over 7,000 antique tags...some have never been previously registered.
A reference for those here living in GA:
