Hi. I'm hoping someone will make my day saying that I have the possibility of having a gold mine on my hands. My dad collected sports cards religiously in the 60s. I have one of many shoeboxes of cards he owned. I estimate there to be about 400 in this box. Here's the thing - I know nothing about them, really. The best I've got as far as trading card knowledge is an extensive history with Pokémon cards. Yeah, pretty sad. I was wondering how I could value all of them? They're honestly from tons and tons of different sets - probably 65% topps. I'm afraid that a standard value book will not cover them all. I'm just very interested in the values. They're pretty much untouched since about 1974, so they're all in about the condition he first got them. Except for a few that he'd obviously traded for. But still, they don't look 35-40 years old by a long shot. Any ideas to get me started? I'm a broke high school student so I can't really afford professional evaluation. Free sites? Guides?
