Here is a PSA pop report for 1960s Topps Baseball 5-cent wax packs having 5 cards in the pack with correct wrapper year and printed in the USA:

          9s          8s          7s          6s          5s          4s           Total

I have tracked these since last Summer when I started my quest for a 1960s Topps Baseball 5-cent wax pack run and the
biggest increase in total number of packs has been the year, 1967, which has increased from 19 total packs to 38 total packs!
