hankronAre they marbles or other?
There are 1968 Major League Baseball marbles that have this basic design (I've never seen one in person). You can find them in the complete as-sold-in-store packages sometimes. I don't know if they made marbles in other years, but those would be from that era.
I may be wrong (I'm no marble expert), but I doubt a single baseball player marble (or rubber ball) is worth a lot of money (in fact, it may be worth little), but they are unusual and far from plentiful. Definitely counts as a baseball oddball item.
