This Music Festival took place Aug. 7-9, 1970 at Jackson, MI. About 200,000 showed up. Festival organizers sold colored chips instead of tickets. There are 9 color variations. The green chip is a different mold. It is Hat and Cane. Don't know about any others, those are the only 2 chip pictures I saw in my search. I would appreciate any help with a value on this one.

Thanks for looking...........Rog
