Unsigned Chanel Rhinestone Pin. . .

Hello - For the life of me - I can't find information on a gorgeous pin I found here in Scottsdale, AZ. The pin is a good sized pin - Rhinestones wih CC design ( Chanel Logo ) Gold back - funky c-clasp - etc. Is is not signed - so that tells me it's older than her signed stuff. Who knows about unsigned vintage designer Pins?
