So, as I’m wont to do, I was browsing through my old sets the other day and perused my 1974 “complete” Topps baseball card set. I finished this set circa 1988. Looked through it two or three times since. But this time I see two Rick Wises! Then I find doubles of another guy! Checked to see if they were misprints or if there was some reason I’d have two of them. Nope. This meant I was short two other cards; the set was not complete. This was devastating.
I keep my complete sets organized by team, not number, so finding the missing cards was a bit tough, but I tracked them down and immediately ordered them. Neither was a star so the cost was minimal.
The whole experience was very disturbing.
Note: sometime after completing that set, I started keeping sets I was building in numerical order, then keeping them by teams only after the set was done. So I doubt that error has repeated.
