A few months ago we told you about the rarest stamp in the world which is worth several million dollars. This June, you can bid on a stamp that is a similar range of value. it's the Pack Strip, shown above, a strip of two 30-reis and one 60-reis stamps joined together (it's named after one of its early owners Charles Lathrop Pack). The strip is an example of stamps from Brazil made in 1842. They are called bull's eyes because the denomination sits in the center of a target-like shape.

The sale of this stamp is part of the auction of the world's most valuable private collection of South American postage stamps. The collection was assembled over four decades by a retired college professor who now lives on an island and will be will be offered in a public auction in New York City and online by Robert A. Siegel Auction Galleries on June 5 and 6, 2008.

The auction also includes from Buenos Aires, Argentina, the only surviving example of the 1859 one-peso "tête-bêche," which is French for head-to-foot, and the term collectors use to describe a pair of stamps that are printed upside down to each other. It has a pre-sale estimate of $400,000 to $500,000. From Chile there is an envelope with a unique block of 14 lithographed 5-centavo stamps of 1854 which is $400,000 to $500,000. From Colombia there is a letter with a 5-centavo and a10-centavo stamp dated September 1, 1859, the first day these very first stamps of Colombia were issued The pre-sale estimate is $200,000 to $300,000.

Our latest Big Giver is Wall Street bond manager, Bill Gross, or as I like to fondly call him, the Philanthropic Philatelist, will offer the Scandinavia portion of his extensive, international stamp collection in a public auction which is conservatively estimated to bring over $1 million. Proceeds from the collection's sale will be donated by Sue and Bill Gross to the Millennium Villages Project at the Earth Institute at Columbia University. The Spink Shreves Galleries of New York City and Dallas will conduct the sale in New York City on May 16, 2008.

The collection has 110 rare and even several one-of-a-kind 19th and early 20th century Scandinavian stamps including an unusual printing 152 years ago of Finland's first postage stamps that shows adjoining images that are upside down to each other, a peculiar placement known as tête-bêche. Charles Shreve of Spink Shreves Galleries says that the piece, a mint condition block of four stamps containing two pair of 10 kopek denomination stamps, the first stamps of Finland from 1856, is one of only three known and estimated to sell for $100,000 to $150,000; however, Shreve expects the winning bid will be even higher.

This isn't the Gross's first shot at stamp philanthropy, the Great Britain portion of his stamp collection was sold through Spink Shreves Galleries in June 2007, and he and his wife, Sue, donated the entire $9.1 million auction proceeds to charity.

The Millennium Villages Project is working to create health, education, agriculture and infrastructure programs to help some of the poorest people throughout the African continent through simple concrete means such as bed nets to fight malaria, seeds and fertilizer to increase food production, the building of schools and clinics, and safe water. The stamps will be displayed for potential bidders at the Spink Galleries in London, England, May 5 – 7, and at the New York City offices of the auction house, May 9 – 12 and May 15.

The rare "Inverted Jenny" stamp, one of the most coveted stamps among philatelists, sold for $825,000 through Heritage Auction Galleries. The 24-cent denomination, a U.S. red, white and blue misprint which shows upside-down Curtis 4-N ("Jenny") biplane, was position number 84 on the original sheet of 100. Heritage recently bought the stamp for $750,000 and sold it to a senior Wall Street executive who is a long-time coin collector. Greg Rohan of Heritage had been the under bidder on the same executive's behalf at an auction last month where another "Inverted Jenny" sold for $977,500. Just goes to prove that sometimes losing out in an auction can be a good thing.
