I just looked at ebid yes there is a lot of stuff there but very few bids.
In my specialty section there are over 80 coins all with absurdly high starting bids for problem and over graded coins.
I noticed that too but have seen the same on E-Bay in a few cases. I'm assuming that the number #2 rating for eBid is based on traffic so, if true, there should be a decent number of customers there. Perhaps selling there with the right product at a good price you could make a little money.
