I can do a round robin of obsolete $1 chips. Do you want just Nevada chips or chips from all over? If all the chips are from Nevada, I can use TCR values, to keep things fair. If the chips are from other locations, what could be done to have the replacement chips be of equal value to the chips they are replacing? I don't want to see some hard to find riverboat or indian reservation chips replaced with Puerto Rico, California card room or cruise ship chips that have been dumped on the market.
