I've kept 2 rip cards unripped 2013,Trout /10 and a 2010 Ubaldo Jimenez /35 (?) ... But the suspense is killing me .... I'd probably keep them unripped, but I started thinking ...What if there's a redemption card in there? I always thought that the value of the cards inside were usually disappointing as compared to the unripped outer cards.
I guess if I saved used tinfoil and used tea bags instead of old comic books and old baseball cards, the difference between a crazed hoarder and a savvy collector is in that inherent value.
