Hi I'm rsb8 and I would like to know what cards are valuable and would be a lot of money to sell them on eBay or something other

It really all depends as there are many cards that are valuable, both new and old. If you have vintage cards from 1960 or earlier, and they are in good condition, most can be worth something. If you have newer autographed cards, or rookie cards of superstars, those also are highly valued. Rookie cards and game worn jersey and/or autographs of Albert Pujols, Michael Jordan, Kobe Bryant, Peyton Manning, and many others are some names for valuable possibilities. If you would like, my signature link has my site and it is free to join and has many articles on this topic. The only way to know for sure what your cards are worth is to look them up specifically based on condition.
