I am in the posession of a $1 Borgata chip with a misprint. The outer ring says $1, the inner circle says $1 on one side and $10 on the other side. I got this chip playing poker at the Borgata, where I won a pot and the chip was in it. According to Borgata floor personnel they had never seen anything like it. I am wondering if this is a rare occurence and if so what the "street"value of a chip like that would be.

Thank you, ivo
