But otherwise, I would argue that the differences are fairly small. That is, everybody plays the game by the same rules and collects for the same psychological, social, and economic reasons. I think there are very few differences between collecting Beanie babies and Renoirs. There seem to be two sets of differences. One is the nature of the object.
Some objects are fairly neutral.
But most objects are clearly feminine or masculine. People tend to collect the objects associated with their gender in society. So the wrench collection in the exhibit is a man's collection used in their work. The peppershaker collection, a domestic item, is more feminine. The second difference is much more subtle and more interesting.
