Fair Prize for Five Descending Cards

A deck holds 97 cards numbered 1 to 97. You draw five without replacement. If the five numbers come out in strictly descending order you are paid WW dollars; otherwise you pay 1 dollar.

Your friend runs the same game with a 63-card deck and insists the fair prize there must be smaller, because the deck is smaller.

What prize WW makes the 97-card game fair, that is, gives it expected value zero?

Answer format: enter an integer.
