I live in Oregon and collect OR casino chips along with NV & CA chips. Where would I be able to find the value of chips in OR?? I have a .50 chip (pink) from Spirit Mountain that I would be interested finding out the value on. Also the purple one as I'm getting that one soon. Any help would be highly apprieciated!!!

Thank you,
Keith

p.s. My father has some great chips on ebay. His username is "giver1st"
