I think this is a neat thread. I similarly think of my collection, and I re-categorize from time to time, such as, from: junk held... to: sell it now--I can't stand to look at it--it's tarnishing the vision of my entire collection. Or conversely, from: I would sell this to finance something else... to: I'm gonna keep this forever, since it inspired me to develop this whole new avenue of collecting.
