Hi Bobby,
First of all it would be helpful to identify the chip (ie. $5 yellow with three orange inserts.) Otherwise I have to scan all the Dunes chips looking for the TCR number. Luckily the "E" suffix made it easy. The "E" stands for error. From the TCR description it looks like the error chip is identical except that it has the correct $5 inlay on one side and a $25 inlay on the other. Certainly the error chip is rarer. Whether it's worth more is in the eye of a potential bidder. Hope this helps.
