I believe grocery trays started in 1960 or 61, pretty sure I have a 61 sell sheet advertising a tray.

In general 5 cent wax packs thru 1960 had 6 cards, then 61 thru 69 had 5 cards. Late 50’s/1960’s Cello packs usually had 12 cards and no gum thru 1969, exception is the 1969 blue 10 cards 10 cents cello. 1970 baseball cellos jumped up to 33 cards and the first time gum was 8ncluded with cellos was 1970 football.
