Baseball-wise, so many have grown...others have fizzled...
The '62 Topps, '55 Bowman, '55 Topps, '60 Topps have grown on me quite a bit over the years.
Among the fizzlers would be '53 Topps. I built this set twice, so it may just be over loved? I used to be nuts for late 70's stuff...that kinda fizzled, too.
The rest of the sets I've always disliked remain disliked
