There may have been nothing on Ebay since the start of the year but there was plenty of material to interest a Jubilee collector which came up in the British auction houses.
Lot 1541 in Spink’s latest offering from the never ending “Lionheart” collection (part 7!) included a Bechuanaland Protectorate 4d on 1/2d with inverted surcharge, which inspired me to publish my census of all the examples I have come across. This example has a small wrinkle at the lower right, and sold for £1’100 plus 25% in fees.
Also from Spink but from their January Philatelic Collectors Series was lots 1032 and 1033, two British Levant covers with “Express D’Orient” labels. 
As far as I’m aware, these labels didn’t pay for any postal service and are basically vignettes/cinderella stamps which were likely created by the enterprising Postmaster of the Constantinople office for collectors. Note that both of these envelopes come with his Post Office cachet and I believe are in his handwriting. The black label is rarer and this cover fetched £950 plus commission. The envelope with the red label was in better condition (and looked better in the flesh than it does in the scan) and sold for £850 plus commission.
Among a nice selection of Niger Coast (of which many items were ex Sacher) in Grosvenor’s March 1st sale was this attractive item. With two 2d and two 1/2d tied by orange-red Benin circular rubber cancels, I couldn’t resist bidding on it. Estimated at £500-600 I guess I was the only bidder as I got it for £500. Unfortunately it was liable to 5% import duty, so commission on the hammer price was 29% (gulp!). They also wanted to charge me £18 for submitting the bid through their website but I’m not going to be paying that!
