A rare cover franked with an error stamp from the old German state of Baden was auctioned in Germany. This rare 1851 cover franked with the Baden 9-kreuzer black printed in error on blue green paper was sold in the June 8 Heinrich Koehler auction.
The cover was included in the June 8 Heinrich Koehler sale of material from the extensive collection of German-born businessman Erivan Haub.
Franked with the 1851 Baden 9-kreuzer black stamp erroneously printed on blue green paper instead of the intended rose paper (Scott 4b), the cover was listed by Koehler with an opening bid of €800,000.
It was hammered down at €1.26 million.
With the buyer’s commission and fee added, the cover sold for €1,524,601.50, or approximately $1.73 million in U.S. dollars.
The cover on offer was mailed in 1851 from Ettenheim to Karlsruhe and was previously owned by three eminent figures in philately: Philipp la Renotiere von Ferrary, Alfred Caspary and John R. Boker Jr.
