Hi Del, If I'm bluntly honest, I would say not that much. Banners are not an easy sale because of size and how hard they are to store. I am not saying impossible, but hard. You've got some good titles there, but it would take a really passionate collector to take them off your hands. I don't know much about price, but I would prob put a couple on Ebay at $100 a piece to see if anyone bites.
Good luck,
T
