IMO, if Gene Tribble had to buy chips for his collection more frequently, rather than trade or get them as gifts, he would have a more realistic view of what they are worth [g].

By the way, if I had paid the price the buyer did for these chips (which I would not), I'd try to sell them for $90-125 each as well. I would plan to hold them for a long time, though, as "Live Long and Prosper!" is probably the only plan that would work.
