Inherited Old Sports Cards
I've always been into trading card games and have made money selling Magic, Yugioh, and Pokémon cards before. My dad used to collect sports cards, mostly football but some baseball, basketball, and wrestling as well. Most seem to be late 80s-2010 era. I'm interested in trying to sell them but they basically are mostly just in a big box lumped together and I don't know much about how to go about trying to sell them. I know most probably aren't worth much but some probably are, for example hes got a Michael Jordan card that is in some hard gold case that I could see being worth something. None of them are graded but I was wondering if there was a website that is seen as like a standard when pricing cards or anything like that similar to TCGplayer for Magic. I was also curious what is the best way to go about selling cards, both valuable ones and bulk. I've heard rookie cards are often valuable if the player ended up being big but honestly my sports knowledge is fairly limited other than the athletes that like everyone would know such as LeBron, Peyton Manning, etc.
