I would guess that most of those folks were around when coin collecting was
in mass vogue, the 30s, 40s, and 50s. No doubt there will be many widows
who will be interested in how much their late husbands' coins are worth. I
hope the guy running the show is honest. If he tells them that there are
140 million coin collectors, though, he's playing fast and loose with the
truth, methinks.
