DJI think Greg is both right and wrong.
There are sellers like SCGaynor and Sandiegowill that have an amazing following and get auction catalog prices for items because of their clientele and their pied piper following.
I've seen Gaynor pull in $350-400 for Ted Williams balls where other "good" dealers can only manage $200 (I bought an authentic one for $145 a few weeks ago) for them on eBay and I bet there are people that buy off eBay just to send to Gaynor or Hayes.
Best of all, no hassle.

Edited to add: David is correct. The above statement is regarding autographs and sports memorabilia which is 'my bad' in this Baseball Card Forum.
