Again, here's the quote that's in question:

In the recent REA auction, for example, the sheet musics entitled the Live Oak Polka and the Home Run Quick Step did abysmally, selling for a small fraction of what they transacted for in the past. For those who collect that sort of thing, those sheet musics represent the pinnacle of 19th century chromolithography. They are quite rare and the particular pieces offered by REA were in exceptionally good condition for the issue.

One could also just as easily argue that Mr. Shanus alerted the public of the undervalued bargains of rare, quality items on REA's auctions, which therefore added interest to REA's future business which would thereby increase their profits.
