You mean if you die in a firey plane crash? That's odd. Why wouldn't you just specify in your will, who they go to and/or what they are worth. Ex. I leave my $834 chip collection to cousin Earl. Also, you could just leave a note with the collection on how much each chip is approx worth. The internet is an amazing tool and our kids are getting smarter and smarter. By the time your collection ends up in your offsprings hands, they will probably have multiple sources of info at their fingertips. Probably virtual libraries and 3-D swap meets etc.
