It looks like a "generic" athletic prize medal to me.
Having your own medal designed is an expensive undertaking, and the production of the dies used to make the medal is a major component of the cost. Engraving the details on each medal is cheaper than making a special die for the medals, if the numbers of medals being issued are small. So for smaller, poorer or more budget-conscious customers, medal-makers like Pinches would sell "generic" medals. They've got lots of blank space on them to engrave the details of the event and person winning the medal.
So to classify it, I'd call it "Generic prize medal, unawarded, made by Pinches".
John Pinches was bought out by Franklin Mint in the 1970s, so they aren't around to ask anymore.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
