I used to be an avid hockey card collector for many years, but I'm not a fan at all of where the industry is today (sports card collecting in general). I hate seeing game-used memorabilia sliced up into little 1x1 squares and sandwiched in the cards. Aside from being a memorabilia collector, I'd just rather these relics be kept in-tact to preserve the history of the sport.
That being said, its not quite as bad when it comes to NASCAR cards with tires or sheetmetal, since theres a lot more of it, but I still don't like seeing that stuff cut up (especially the firesuits).
