Football rookie cards? how much are the following worth?

I'm sorry to tell you this, but your collection is not worth too much (two to five dollars). Topps makes so many football cards that even the rookies are not extremely valuable, even in mint condition. To make your collection more valuable, you may want to grade your cards with Beckett (BGS) or Professional Sports Authenticator (PSA). They'll give your cards a grade (not everyone will believe your cards are all mint). It'll cost you some bucks, but the cards will be preserved very well (especially with BGS). The real reason they're not worth that much is that they're not really special at all. Topps makes tens of thousands of the cards you own, and i believe at least a couple thousand people have cards in mint condition. Serial-numbered cards are unique (none have the same number, and only that many were made). It's a good collection for yourself (great players!), but don't expect any to sell for more than a dollar apiece (expect if you grade them). (I think the Fitzgerald and the Roethlisberger can be worth grading if in mint condition; both are Hall of Fame caliber players. The older cards, if mint, can also be worth a little more if graded.)
