"For my traders, the opposite is true; the market value and intrinsic value are important to me to insure any trades I make are relatively fair to both trading parties"

This is more true in this hobby than many people realize. I have never seen a hobby driven by such honest people. No where else would you see the free flow of money and product without worry of getting ripped off. That is why it is important to know the value of each chip that you wish to trade or sell. People won't continue to trade with others who set the wrong (too high)value for their product. Trades are rarely perfect but both parties need to feel that they got a fair deal in the end.
