What he'll have left is pretty much worthless. First off, he originally announced in the PR where he stated he AND PARTNERS bought the collection that it had about 10000 items. About a week before the auction he claimed it had 20000 items, then about a day or two later 30000. With RA its always best to believe the smaller number of multiple claims.
When I built my spreadsheet this weekend I looked at every lot and recorded how may items it contained. I came up with over 7500 items, and there were several lots that it was impossible to determine how many items there were, because no number was given, yet the item clearly indicated large number of items - some probably several hundred pieces.
Now if you go to the USXP website and see the description RA gives, if you go to the last PDF, you'll see he lists only 1800+ items (some multiple items per listing, just as with the auction items), and states that another 1900 existed that weren't worth noting.
So, it pretty much looks like he has gotten every item that the auction house thought there was a chance of selling into the auction.
Now, clearly there are going to be a lot of items that didn't even get 100.00 minimum bid (a stupid limit). But I don't think any auction house will hold another auction to try to sell them (he could just try selling them on eBay himself).
Good luck to you...
P.S. Yes, my speadsheet is adding up the items as I enter the prices they get.
