HI DON, I THINK THAT THE CHIP RACK AND JAMES CAMPIGNIA'S BOOKS ARE A GREAT GUIDES, FOR THE COLLECTORS AND THE DEALERS BOTH. I ALWAYS REMEMBER THAT A CHIPS I ONLY WORTH WHAT SOMEONE IS WANTING AND AGREEMENT TO PAY. THE RARE AND SCARES HIGH DOLLAR STUFF TO ME IS THE BEST, BECAUSE EVERYONE DON'T HAVE THEM, AND THEY USUALLY HAVE BEEN LOW IN NUMBER LEFT TO FIND...AND MOST HAVE SPECIAL MEANING TO ONE'S COLLECTING THAT AREA OF CHIPS. CONDITION ON THESE CHIPS IS KING, AS WELL AS LOCATION OF FINDING YOUR GEM CHIPS FOR YOUR SPECIAL COLLECTION. I FEEL EVERYONE IS DIFFERENT AND EVERONE COLLECTS THAT WAY TOO. SO, IF IT IS RARE AND SPECIAL CHIPS, THE VALUE IS A MEETING OF THE MINDS FOR THE DEALS! NOT SOME EVERONE- GOT IT CHIPS! JUST MY POINT OF VIEW. SEE EVERYONE AT THE CONVENTION! RONNIE.
