Treskilling Yellow

Treskilling Yellow is a three-skilling Swedish stamp that was misprinted in 1855. Only one sample of the "Treskilling" Yellow” (Swedish: Gul tre skilling banco, literally "yellow three skilling banco") is known to exist. On July 13, 1857, this stamp was canceled at Nya Kopparberget (today known as Kopparberg), roughly 150 kilometers (93 miles) from Uppsala.

The stamp was supposed to be green, but due to a printer error, it was printed in yellow, which was the color specified for the eight-skilling stamp. Its exact worth is unclear. It was previously sold for $2.3 million in 1996, but little is known about its current value. The last time it was sold was in 2010. Before the auction, the stamp was estimated to be worth between £1.29 million and £1.73 million by the auction house. The winning bid was not revealed.

Three rare stamps are depicted in the 1963 film “Charade”, one of which is a red Fyrskilling issue. This one, like the real-life Treskilling Yellow, must be a typo because the authentic Fyrskilling stamps were blue, not red, but a misprint of this type is difficult to achieve using standard printing procedures. The stamp was printed in 1854 (one year before Sweden began producing stamps), and the philatelist in the film valued it at $85,000 (adjusted for inflation, this is nearly $700,000 by 2021).

Price: $2.3 million
