I know someone that has one of the Horseshoe Tunica error chips with $2.50 printed on one side of a $5 chip. Does anyone know the worth of a chip like this? I know it's whatever someone is willing to pay for it.. but.. I'm wondering if there is a set value. I don't want to offer to much or to little for it. I was thinking $7.50... $5 for one side and $2.50 for the other.. but seriously, I hope someone has some kind of educated opinion. Thanks.
