Get a few rolls of pennies from the bank. They're almost certain to have some 2003 coins, probably some 1989's, 1990's, 1995's, 2000's, 2002's, 2004's ... well, you get the picture. And they're all worth just what the bank charged you for them.
None. Unless the coin has an "S" mintmark, it is a normal copper-nickel coin made out of the same composition as the dime, quarter and half-dollar and is only worth $1.

Assuming your silver proof quarter does not have any visible nicks or scratches, it is worth $3-$4 -- otherwise it's worth about $1 (Deleted my previous update. Since the S mint mark only appears on proof coins this could not be a circulation strike. The first answer above is correct as it stands.)
