[Apokalypse]

Hi.. Could I please ask a couple of questions without being called an idiot? Here it goes.. First: I have been a huge hockey fan my whole life but have never had much interest in buying or collecting cards...until about a year ago when a good friend passed away and left his cards to me. I began looking through them and discovered the fun and great memories of the players and games I grew up with that these cards gave me. Now I am hooked. I couldn't care less about the value of these cards but I would like to know how I can tell if the card I'm looking at is a rookie card or not... Does it have to say "Rookie" on it? I have hundreds that do.. But hundreds more that don't but only have 1 year of stats on the back.. The value isn't important to me but it might be to my son in the future when I give them to him.. And I worry that I may not be storing some potentially valuable cards correctly..
