Most people on this board know this, but just in case... to anyone who may think to flip any high denom chip to make a few bucks, Las Vegas Casino's do not redeem high value chips to just anyone. Even if its a live chip, you may have a tough time redeeming it. Most of the time, you will need to establish yourself as someone that plays at that $ level or they will need to see proof that you won the chip. The casino generally doesn't care if you found it or bought it at a discount. Just be cautious.
