I don't have Ebay skill, but i doubt that you would make more money, if you sell them in a bunch..
It would probably be too expensive for some buyers, but not if they were seperate. More bids.
Think in the mind of the buyer. Who would want a bundle of *s for a large cash sum? Who would want choice of an individual *? Use the selling tactic that will generate the most interest.
Doesn't matter. Stuff like that will generate bids, so you should list them all with a $0.99 starting price and let the market drive them up.
You will also get a lower listing fee.
Did you mean by how much you got regarding whether you should sell them or not because you may get more elsewhere? Must feel sort of scary to put *s up for $0.99
