can comment here or on Twitter for hat suggestions for Hatpack 2 <| sep |> Honestly , I haven ' t kept up with card values the last several years , so I ' m not up to date on what the card companies are doing nowadays . But we ' re talking about older sets here , which I didn ' t specify very well that I was referring to . I used to collect older cards , and my goal was to either obtain full sets from each year , or put them together piece by piece , which is why I paid so much attention to the full set prices . My crown jewel , so to speak , was the Topps set with the Robin Yount and George Brett rookies , ' 75 I believe . Also had all of the ' 68 Topps set except for a mint Nolan Ryan rookie , couldn ' t afford any better than a creased one with bubble gum stains to complete the collection .
