When it comes to certain collectibles, the error is worth more than the perfect copy. Tomorrow an auction puts over 3,000 mistakes up for sale. A stamp collection gathered by a Pittsburgh stockbroker, the late Robert H. Cunliffe may bring in more than $4 million. Dallas-based Spink Shreves Galleries is auctioning off the collection on June 18 and 19 at the Spink Shreves New York City Auction Galleries. Charles Shreve, president of Spink Shreves Galleries says that it is the most comprehensive collection of inverted centers and printings ever created.

Inversion occur when there are several different colors printed on a stamp in different press runs. Most of the time these printing switches go off without a hitch but everyone in a while a sheet gets flipped upside-down between press runs and that's when the magic happens. These rare inversions become instant collector's items.

Cunliffe's collection includes an "inverted Jenny," perhaps the most famous of the inversions. The U.S. stamp from 1918 features an upside-down biplane. We've seen some inverted Jenny stamps sell for nearly a million dollars but this one is expected to bring of at least $125,000 to $150,000. Shown above is a strip of four U.S. stamps from 1901 featuring an upside-down electric automobile which may sell for over $300,000.

At the Spink Shreves Galleries in New York, an auction proved that stamp collectors are still willing to spend money. A stamp collection centered on President Abraham Lincoln brought in almost $2 million (including commissions).

The stamps came from a collection by a retired executive from accounting and consulting firm KPMG. William Ainsworth inherited his father's stamp collection more than 40 years ago. Until 1977, he paid it little mind, but a meeting with a former postmaster general changed his thinking. Ainsworth began to build upon the already substantial collection, with a particular focus on Lincoln.

The collection included 19th and 20th century American stamps with the sixteenth president, along with tax stamps, private issues, proofs and test printings. A mint-condition set of 90 cent stamps (issued in 1869) pulled in $149,600, and a 1909 registered letter with a pair of blue 5 cent Lincoln stamps (sans customary perforations) was good for $77,725.

Postage stamps have featured some of the best art and most beautiful designs over the years, and now your favorites can be yours to enjoy for longer than just the time it takes to send a letter. P.S.

The philanthropic philatelist is at it again. Wall Street money manager, Bill Gross is selling off another portion of his extensive stamp collection in a public auction estimated to bring over $1.25 million. All proceeds from the sale of his British Empire stamps will be donated by Sue and Bill Gross to the Millennium Villages Project at the Earth Institute at Columbia University. Spink Shreves Galleries is holding the sale in New York City on October 3, 2008 and pre-auction displays of the historic stamps are planned in London and New York.

This is the third time Gross has offered portions of his collection to raise millions of dollars for charity, and the second time the Millennium Villages Project has been selected as the recipient of the proceeds. This part of the collection has 138 items; rare and one-of-a-kind stamps and covers (envelopes with canceled stamps) from across the globe of the 19th and early 20th century British Empire. There are rarities from such places as Australia, the British West Indies, the Cape of Good Hope, Cyprus, Gibraltar, India, Malta, and Mauritius. Shown above is a trial printing "square pair" of 1863 Cape of Good Hope triangular-shaped, carmine red, mint condition, one-penny denomination stamps with a pre-sale estimate of $80,000 or more. The auction has its own website with more details here.

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.
