According to the Winter 2013 issue of Fine Books & Collections, a copy of the first edition, first issue of Arthur Conan Doyle's A Study in Scarlet, the first published Sherlock Holmes story, sold for over $50,000 in October of 2012, which is more than double any previous sale price for the title.
A Study in Scarlet originally appeared in the 1887 Beeton's Christmas Annual, copies of which have sold for as much as $130,000 at auction.
(Oddly, the numbers in the article linked to the images don't match up with the numbers in FB&C, but they are all very large numbers.)
Another huge price for a Sherlock Holmes item in 2012: the manuscript of "Mr. Sherlock Holmes to His Friends" went for $80,500 in September.
