I think this is typical of Worldwide.
Back in November of 2012, WorldWide had a 9.2 copy of Catman Comics #1 listed on their site as "SOLD" around the time it showed up in a ComicLink auction. I believe it was priced at $6,000. It only fetched $4,100 in the CLink auction, and all records of the sale disappeared from CLink's site within about a day.
I sent an e-mail to Josh Nathanson about it, but he couldn't offer an explanation.
Lo and behold, @Cat-Man_America later acquired the book from—guess who—Steve Ritter of WorldWide.
