I am fairly open to people about my coin collecting because I'm trying to get people my age more interested in it. I keep all mine in a safe deposit box and keep very few at the house. I never tell people what I keep at home but I will say all of it is more or less junk. I don't openly say what all I have but I do show off good deals and NEWP's to my closest friends and co-workers. Most of my "showing off" comes from the G-4 1834 Large cent, '64 Kennedy, and '36 Merc I carry around in my pocket though. Those seem to get people interested enough.
