Dull Rose
The Dull Rose is a Ceylonese postage stamp that is considered to be the rarest and most valuable stamp issued in the country. 7000 stamps were issued on 23 April 1859, bearing a face value of four pence. Three others, the 8 pence, 1 shilling & 9 pence, and 2 shilling & 9 pence were issued on the same date as part of a series. These featured a left-facing depiction of a young Queen Victoria in an octagonal framing.
A mint condition original issue Dull Rose was sold for $71,875 at a Cherrystone Philatelic Auction in January 2008. Very few mint condition stamps are known to be in existence, valued at £70,000 - £100,000, while used ones are valued at about £4,500.
