I know little about chips but I recently came across a $50 chip that is only marked CASINO & $50. With no casino name I am suspecting it is from a home or similar set. Just my luck but I woul;d like this verified if possible. The chip has blue & white border, The words casino opposite each other & $50 on opposite sides. There are four positions of cards with four suits & the center is a heart. Any help appreciated.....
