These were just noticed in the casino but were issued in 2012. There is a set of 4 for the Jazz Festival but I could only locate 2 of the 4. Also there is an Independence day chip for 2012. THe chip that shows "detroit Jazz FESTIVAL" is a common back for the set.

Chips are $8.50 each, mailed. Scan shows the wear on the chips. If interested, email me at albertscalzo@gmail.com.

Thanks for looking!
