Certainly not!

However...when dealing with obsolete chips, it can take some time to determine the true market value (TCR & C&W are only guides, you know...). For example, looking at one chip from each collection, both with equal TCR/CW values, I'd still have to do further research to make sure that they'd actually sell for the same amount. Could take years of research...tracking ebay auctions, looking at chips for sale on websites, that sort of thing. Any chips that I couldn't find for sale, well, I'd just have to hang on to 'em for further research! Wouldn't want either of you to feel like you didn't get a fair deal, you know!
