How much is my Albert Pujols, Ozzie Smith, Lou Brock, and Colby Rasmus Autographs worth?

The answer can vary from city to city,condition of the piece that is autographed, if a certificate comes with the autograph, how old the autograph is, what type of item is the autograph on.Also,keep in mind, is the person alive,deceased,active player,retired, if you have Albert P., chances are not much, because he's still active, has signed alot of autographs, but,say,,you have a rookie Babe Ruth card, in perfect condition, you could have some money. Reasearch some collectors, go to a few sporting conventions, sounds like you may be near St.Louis,so bigger the city, more places will have a price list. Use the internet,check e-bay,see who has autograph items up for bid,see how much people are bidding, see a sports collector store,ask around.it just various on where your at, .condition of what's signed,if a certificate comes with it , and who signed what.
