My pricing depends first, on how much I pay for the chip; second how many were issued and, of course, the condition of the chip. As you know, I prefer to trade rather than sell unless I have quite a few and need some cash to help pay for others<g>. For example, until you ID'd the LDG/631 I had been trading it at a $20 value. Now that I know there were only 100 made, I would increase my trade and sale price. It really is somewhat of a guessing game. Hope this helps somewhat and would like to hear what others have to say.
