I work as a appraiser for sport products and I believe the football signed by Gale Sayers is worth about $100 at this moment due to the fact that there is a lot of these balls out there. But there is...
Around the prices of $500.00 - $1000.00 depending on condition
what i do is go to a card shop and ask it always works! ;)
