Like you, I'm 65. Unfortunately, I can't help with your question very much. I don't recall buying all that many packs of cards. My main collecting dealt with going to the commissary with my mom and picking out which Post cereals to buy. Although there are variations in some of the Post cards, I wasn't aware of them at the time and focused only on whether I had the player's card already or not. I'm sure I probably also had some '63 Jell-Os thrown in the mix but I don't recall if I realized they were different sizes. My wife claims I'm not very observant, I'm sure I was even less so back then.
