I should have mentioned this the other day. The seller, Dee Oakley, inherited some chips from her Aunt. She had no clue what they are worth. Started the auction at 1.99 for the Dunes chip. Right away someone sent her a message and graciously offered her 150.00 for the chip. That peaked her interest and she found the facebook page Casino Chip Collectors, where she posted the chip and was informed of the value. She then posted better pics of the chip. She has a few others for sale, auction ends Sun at around 8am PST. She seems like a very nice lady and said she will use the money for her daughter who starts college this fall.
