Recently StamNews.com got information that the series of blue magenta stamps was sold for more than €6 million just after the British Guiana one-cent magenta had stolen the spotlight. Many collectors were just as interested in the balance of John du Pont's British Guiana collection, which went on the block just a few days later in a sale conducted by David Feldman.
The sale realized more than €6 million (US$8.75 million) with every single lot selling for more than the pre-sale estimate. While the sale was conducted in Geneva and bids were in Euros, this report converts prices realized to Canadian dollars, including buyer's premiums.
"In 40 years as an auctioneer, I have never had the experience where every single lot was underbid to an astonishing multiple of the original estimate, leaving no lot unsold," Feldman said.
Because the four-cent stamps were used for regular correspondence, a large number of them survived.
A four-cent black on blue used on cover, with the initials EDW for E.D. Wright, a postal clerk at the time, realized US$420,000. It was the most expensive stamp of this series.
