In "President Cleveland, Where Are You?," what does Jerry do when he finds a Grover Cleveland card?

He trades in his complete set of president cards for a new baseball glove.

He sells the card and gives the money to Armand so he can go to the dance.

He rides his bike to the North Side to trade it for a Warren G. Harding card.

He asks the storeowner if he needs two Grover Clevelands to complete the set.
