There have been a few games over the years (mostly bowl games I think) where a special coin was created with both teams logos instead of heads/tails. Why wouldn't a school get a bunch of special coins with team logos made up for each home game, use them for the game, and then auction them off as souvenirs? The coins couldn't cost that much to make, depending on the quality.
Sure, there would be losses that the visiting teams fans might care more about. But who cares where the money comes from?
