Mine are packs. My mom suggested to me when I started collecting that I save one pack from each year. I reluctantly did so. That gave me 1986 on. I started backwards on my own. The 1971 is just too pricey right now, as well as the 1960's stuff. The 1950's stuff is just ridiculous. I did pick up a stack of 5-6 1951 red back packs, and one blue back one about 15 years ago. Only paid $35 each for the reds. But other than those, I don't have any before 1970. I do have both variations of the 1974 pack, the "Bonus Team Checklist" one and the "All 660" one. Do you have the version of the 1994 pack that had sticks of bubble gum in them? They are a variant of that year that most people haven't seen. They were marketed in retail establishments like Target. Didn't sell well. You might also look for the 1985 one that doesn't have the year on it. That one is pretty common. I don't think they command any premium, but they are another variant.
I have never seen the 1989 plastic. I'll have to look for one.
Here is my little shelf.
