Wow, did you not know that the $1,000 bill could probably be sold for upwards of $1,500 ?? They "retail" for $2,000 and up and as I write this there's one on eBay with a "buy it now" price of $1,799. Even in 2006 these bills commanded a premium and I wouldn't be surprised if the price was about the same then-- give or take a couple of Benjamins.
