I HAVE A CHIP (SEE BELOW) FROM THE AMBASSADOR HOTEL. HERE IS A LITTLE BACK GROUND. THE L. A. AMBASSADOR WAS BUILT IN 1921, THE PALM SPRINGS AMBASSADOR WAS BUILT IN 1929. I RECEIVED THIS CHIP ALONG WITH OVER 2000 CALIFORNIA CHIPS. SO, THERE IS NO REASON TO BELIEVE THAT IT IS NOT A CALIFORNIA CHIP. ONE OF THE WEB SITES I FREQUENTED CLAIMED THERE WAS A SECRET ROOM WITH A BAR AND A POOL TABLE, SURE SOUNDS SUSPECT TO ME. ANY OF YOU CHIP DETECTIVES OUT THERE CARE TO TAKE ON THIS CASE, I AM SURE MR. PHELPS WON'T MIND...LOL HERE IS THE PICTURE FRONT AND REVERSE, NOTICE THE TWO DIAMONDS, I BELIEVE IT COULD BE USED AS A POKER CHIP, BACK THEN.
