Do you know any? How did you meet them? How did they acquire their coin or coin collections? I think many of those stories you read of some guy or gal with a massive collection or an extremely rare coin (Didn't some old Englishman have a AU 1796 Half Cent that his relatives found sell and sold at auction just a few years ago. I think I recall that story correctly) get them almost by happenstance. As though they are collectors of non-coin related items and just acquired the coin(s) in some old time deal they don't even remember.
