You won the dollar amount mentioned on the card, so $10 for Mays and Mantle, but only $1 for Babe Ruth. Damascus (race horse) and Parnelli Jones (race car driver) were $1000 prizes.
Interesting site I found it on:

And for some odd reason (likely either their confusion or passed down from a TPG error), VCP has Roger Maris as part of this set. He was in the Atlantic Oil set, not American.
