the trade sessions have always been fun, sociable times that gave me an opportunity to meet people AND trade some chips. I have never had anything but common chips with me at the trade sessions. Don't ever feel bad about taking time to look up values. Anyone who wouldn't want you to feel that you got a fair trade by allowing you time to reassure yourself of value is someone you don't want to trade with anyway. Please come to the trade sessions and introduce yourself. You might even find a chipper or two to trade with. Mostly, HAVE FUN!
