Showing your collections/room off to others

[steve B]

I've shown friends some stuff, usually when they ask after a casual mention like saying I was at the card show (or other show)

I usually show them a card from each decade and talk about how it represents that time period by it's technology and art.

I rarely talk value except as a social artifact.

But my family knows what the few valuable items are, or the ones that are special to me for some reason despite not having much value.
