Value of photo negative

A co-worker of mine is in possession of the original 35mm negative of Keith Smart's last second jump shot to win the 1987 NCAA title for Indiana. Does any one have an idea of its value?

Yeah I would say $5-15 or so. Unless there's some crazy provenance or it was used on the cover of SI or something, I don't see it being worth a whole bunch. But what do I know?
