1974 S (Proof) Quarter is worth $1.50.
Because of the silver content in the dime, quarter(s) and half dollar.
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.)
If you got in change spend it, in 1968 the only mint marks used were D & S a coin without a mint mark was struck in Philadelphia.
The value of a 1974-S quarter typically ranges from 25 cents to a few dollars, depending on its condition and whether it is a regular circulation coin or a proof coin. Uncirculated or proof versions can be worth more, often between $3 to $10 or higher for well-preserved examples. For an accurate valuation, it's best to consult a coin dealer or reference current numismatic guides.

A proof what? Cent, nickel, dime, quarter, half dollar, or dollar? I'm hoping to get $8 or $9 for a whole set at an auction this weekend.
If it was found in change, 1 cent. If it's a proof or uncirculated coin in its original holder it's worth about a quarter.

A normal 1991 S proof set is worth $9. A 1991 S proof prestige set is worth $51.
From 1968 on, only proof quarters carry an S mint mark. A proof quarter would look much like an ordinary circulation quarter, except that it would have a much shinier and lustrous surface plus of course an S next to the bow in Washington's wig.
