As I recall Topps was supposed to have gone into the market and bought 3 full set runs, 1952 to 1991. One run was the grand prize if you drew the right Game Winners card. Other winners cards were good for one of the full sets. The third run, 1957 on was distributed in packs. Not sure how many may still be lying around in unopened packs. From 52 to 56 there were redemption cards in packs. Not sure how many in those years were not redeemed. I also seem to recall that some high value post 56 cards also had to be redeemed and were not included in packs, but not sure
Still looking for 3 of the serial numbered game cards to complete a run
