How much should I sell my baseball cards for?

Card value is VERY different based on exactly what you have. I would seperate yours based on team -or- player. I would also look closely on certain stars that could be worth a lot more than 10 cents each. (i.e. Jordan, Kobe, Jeter.) It is really difficult to give you a for sure answer on how to sell based on what you have. My only advice is to seperate them into lots of players and teams you think would sell. If you think they are junk, they probably wont sell. You could also try craigslist and list them all for 1 price, see if anyone nibbles. I always reccomend craigslist because you never know who is looking for stuff like that and there a ZERO sellers fees on CL.. Good Luck!
