Is this worth it?
There are two types of sellers on Ebay- those who know they've got a hot deal(and put it on a low bid, it still takes off running + exceeds their wildest expectations) and those who start out with a discouraging high starting bid- and it goes nowhere.
I much prefer the former- if you don't sell something, you're just giving money (auction fees) away to Ebay.. That's probably 90% of their revenue. That auction, will probably be in the later category.
I collect autographs too(not just famous PWD's, pretty much anybody) but I don't think that's worth it. (out of my price range, anyway)
