UM Hockey "Garage Sale" and Jersey Auction

http://www.mgoblue.com/sports/m-hockey/spec-rel/040310aaa.html Has anyone noticed the price ranges for the jerseys available? (I assume this isn't the first year of the jersey auction.) I'd like to get an idea for what a bid should be in order to be close to winning. I'm thinking popular jerseys would fetch over a grand, but does the minimum ($150) ever take a "MISC" jersey? also, what type of things are sold at the "garage sale"? Official/used UM items, generic hockey items, or is it mostly the apparel that didn't move at Yost (hoodies/t-shirts/hats)? Any assistance is appreciated.
