RARE STAMP

The "Treskilling" Yellow, or three schilling banco error of color (Swedish: Gul tre skilling banco, literally "yellow three skilling banco"), is a Swedish postage stamp of which only one example is known to exist. This stamp was canceled at Nya Kopparberget (now known as Kopparberg), about 150 kilometers from Uppsala, on July 13, 1857.[1]

The Mauritius "Post Office" stamps were issued by the British Colony Mauritius in September 1847, in two denominations: an orange-red one penny (1d) and a deep blue two pence (2d). Their name comes from the wording on the stamps reading "Post Office", which was soon changed in the next issue to "Post Paid."[3] They are among the rarest postage stamps in the world.
