Just off the top of my head, here, which means you're getting the overflow that doesn't drain into the normal cesspit of my mind; but I think, other then "attic treasures" - which primarily sh/w/could be music related in this crowd, I would think; what I see as the most likely objects for the MC auction would be handdicrafts; those one of a kind items such as many of the items which have been offerred are.

Does that make any sense?
