Arthur Gray (philatelist)

Gray died on 22 May 2015 after suffering from a prolonged period of ill-health.

When his collection of "Roos", as the kangaroo and map stamps are colloquially known, was sold at auction in New York in 2007, it grossed $US 5,584,000 (including the 15% buyer's premium) with all 849 lots sold. Gray's 1913 £2 black and red kangaroo and map stamp with lower sheet selvedge with JBC monogram reached a world record price for a single Australian stamp of $US 138,000 despite being hinged, and having a crease and some toned perforations. One dealer observed that with an estimated value without the selvedge of only around $US 4,500, the buyer had paid $US 133,500 just for the monogrammed slip of paper attached to the stamp. Gray had expressed the wish that the collection be dispersed on the open market in order to allow new collections to be formed, rather than be sold to an institution as that of fellow Australian collector Ray Chapman's had.

Arthur William Sinclair Gray FRPS (14 April 1939 – 22 May 2015) was an Australian philatelist known for his collection of pre-decimal Australian stamps, particularly the "kangaroo and map" issues. A collector from a young age, a successful business career gave him the means to build a gold medal winning collection through determined auction bidding in which he hated to be unsuccessful. He was active in organised philately being a fellow of several philatelic societies and was a leading figure in the purchase of the Brusden-White philatelic business. The sale of his kangaroo and map stamps at auction in 2007 was a complete sell-out and achieved a world record price for a single Australian stamp.

Arthur Gray was born on 14 April 1939. He was a stamp collector from a young age and would ride to local post offices on his bicycle to buy imprint blocks of the current stamps.
