The "what if I bought all those for $5 each in the past" scenario happened in just a few years for me. I was an 80s kid and starting getting into the business in '88 (after somehow bumping into how much my "old" early-mid 80s cards had really started to go up.) It was during that very short period of time when the junk boom had just begun, but people didn't care about any sport but baseball quite yet.
Three or four years later those Michael Jordan rookies (that just gathered dust in the cases at that first show with $4 price tags) were selling for 400. Similar explosions with Montana ,Gretzky, Lemieux, and so on.
Not what I expected to already have a "what if" story like that by just age 18
