1962 Dag Hammarskjold Invert Error (Scott #1204)

A Stamp That Rewrote the Rules of Philately

In the world of stamp collecting, errors are gold. A misprint, an inverted color, a misaligned perforation can transform a four-cent piece of paper into a five-figure treasure. That is precisely what should have happened with the 1962 Dag Hammarskjold commemorative stamp. Instead, Postmaster General J. Edward Day made one of the most controversial decisions in American postal history, and in doing so, created a collectible that fascinates philatelists to this day.

The 1962 Dag Hammarskjold Invert Error, catalogued as Scott #1204, is more than just a stamp with an upside-down color. It is a story about government power, collector outrage, courtroom drama, and the very nature of what makes something rare.

The Man Behind the Stamp

Dag Hammarskjold served as the second Secretary-General of the United Nations from 1953 until his death in a plane crash on September 18, 1961, near Ndola in what was then Northern Rhodesia (now Zambia). He was traveling to negotiate a ceasefire during the Congo Crisis when his DC-6 aircraft went down under circumstances that remain debated to this day.

Hammarskjold was a transformative figure in international diplomacy. He expanded the role of the Secretary-General from a largely ceremonial position into an active force for peace. He was posthumously awarded the Nobel Peace Prize in 1961, one of only two people to receive the honor after death.

The United States Post Office Department decided to honor Hammarskjold with a commemorative stamp, issued on October 23, 1962, the anniversary of his appointment as Secretary-General. The four-cent stamp featured a portrait of Hammarskjold alongside the United Nations headquarters building in New York, printed in black, brown, and yellow.

The Error That Started Everything

The stamp was printed on the Bureau of Engraving and Printing's Giori press in plates of 200 subjects. The design required multiple color passes, and during one production run, the yellow background was printed inverted relative to the black and brown image and text elements.

A New Jersey jeweler named Leonard Sherman purchased a sheet of 50 stamps at his local post office and noticed something extraordinary. The yellow background on his stamps was upside down compared to the normal printing. Sherman had stumbled upon what every stamp collector dreams of finding: a genuine invert error.

Sherman immediately recognized the potential value. Invert errors are among the most prized stamps in philately. The famous 1918 Inverted Jenny (Scott #C3a) had already established that color inversions could be worth astronomical sums. Sherman saw dollar signs.

Day's Folly: The Government Strikes Back

What happened next was unprecedented. When word of the error reached Postmaster General J. Edward Day, he made a decision that would earn him the lasting enmity of stamp collectors everywhere. Rather than allowing the error to remain rare, Day ordered the Post Office Department to intentionally reprint the stamp with the yellow color inverted.

Day's reasoning was straightforward, if unpopular. "The Post Office Department is not running a jackpot operation," he declared. He argued that allowing a government printing error to create windfall profits for a lucky few was not in the public interest.

The Post Office printed approximately 40,270,000 copies of the intentional invert, designated as a "Special Printing" and released to the public on November 16, 1962. The original normal stamp (Scott #1203) had a print run of 121,440,000.

The decision became known as "Day's Folly" among collectors, a name that stuck to both the stamps and the controversy.

The Courtroom Battle

Leonard Sherman did not take this lying down. He obtained a court injunction against the reprinting, arguing that the government was deliberately destroying the value of his discovery. Unfortunately for Sherman, the legal machinery moved too slowly. By the time the injunction was considered, the 40 million reprints were already rolling off the presses.

Sherman did receive one small consolation. The Post Office Department provided him with an official affidavit confirming that his sheet was from the original error printing, not the intentional reprint. This distinction would prove important for collectors.

In 1987, disillusioned by decades of watching his potential fortune evaporate, Sherman donated his original sheet to the American Philatelic Society. The dream of owning a valuable stamp error had been thoroughly dashed by government intervention.

Telling the Difference: Original vs. Reprint

One of the most intriguing aspects of the Hammarskjold invert is the near-impossibility of distinguishing an original error from the intentional reprint. The stamps were printed using the same equipment, the same inks, and the same paper. To the naked eye, and even under magnification, they are virtually identical.

The only reliable way to confirm an original error is through provenance documentation. A stamp with a clear postmark dated before November 16, 1962 (the release date of the reprints) can be authenticated as an original. First day covers from October 23, 1962, bearing the inverted stamp, are particularly desirable.

In 2005, a Hammarskjold invert on a first day cover sold at Siegel Auctions for $3,500, confirming it as an original printing. Without such documentation, any individual Hammarskjold invert is assumed to be from the much more common reprint.

Value Guide

The Hammarskjold invert presents an unusual value structure for an error stamp:

Condition and Grade Scale

Condition Grade: B+ (Reprint) / A (Authenticated Original)

The reprint is one of the most affordable "error" stamps in U.S. philately. The authenticated originals, however, carry significant premiums due to their documented rarity.

Why Collectors Still Care

Despite its low monetary value in reprint form, the Hammarskjold invert remains a beloved collectible for several reasons.

First, it is a genuine piece of postal history. The controversy it generated led to lasting changes in how the postal service handled printing errors. Never again would a Postmaster General deliberately flood the market to prevent collector profits.

Second, it tells a great story. Few stamps come with courtroom drama, a Mad magazine parody (the magazine printed a version with a crying Leonard Sherman replacing Hammarskjold, with money flying away), and a decades-long debate about government overreach.

Third, it raises philosophical questions about value and rarity. Is a stamp valuable because it is rare, or because of the story behind it? The Hammarskjold invert suggests the answer is both.

The Normal Stamp: Scott #1203

Collectors should note that the correctly printed Hammarskjold stamp, Scott #1203, is also quite affordable and makes an excellent companion piece. The normal stamp shows the yellow background in its intended orientation, creating a warm golden tone behind the dark portrait.

Displaying both the normal and inverted versions side by side allows collectors to appreciate the subtle but unmistakable difference in the yellow color placement.

Collecting Tips

For new collectors, the Hammarskjold invert offers an excellent entry point into error stamp collecting. Here are some practical tips:

Buy complete sheets when possible. A full sheet of 50 stamps in mint condition is an impressive display piece and can often be found for under $50.

Look for plate blocks. Blocks of four stamps with the plate number in the margin are more desirable than individual stamps and typically sell for $2 to $5.

Document your purchases. Even though most examples are reprints, keeping receipts and provenance records is good collecting practice.

Consider a first day cover. While authenticated original FDCs command thousands, there are also commemorative covers from the November 16 reprint release that make interesting additions to a collection.

Store properly. Use acid-free mounts and keep stamps away from direct sunlight, humidity, and temperature extremes.

The Legacy of Day's Folly

J. Edward Day served as Postmaster General from 1961 to 1963. The Hammarskjold controversy was perhaps the defining moment of his tenure. While his intention was to prevent profiteering, the decision permanently altered the relationship between the postal service and stamp collectors.

The episode contributed to the establishment of clearer policies about how printing errors would be handled. It also reinforced the importance of the Philatelic Sales Division, which would eventually become the primary channel for collectors to obtain new issues.

For Leonard Sherman, the story had a bittersweet ending. He never profited from his discovery, but he gained a permanent place in philatelic history. His donated sheet remains a centerpiece of the American Philatelic Society's collection.

Market Outlook

The Hammarskjold invert reprint is unlikely to appreciate significantly in value due to the enormous quantity printed. However, authenticated original errors continue to command strong premiums, and the gap between original and reprint values may widen as documented originals become scarcer through attrition and institutional acquisition.

For investors, this is not a stamp to buy for capital appreciation in reprint form. For collectors and history enthusiasts, it remains one of the most compelling stories in American philately, available at a price that almost anyone can afford.

The 1962 Dag Hammarskjold Invert Error is proof that in collecting, the story behind an object can be worth far more than the object itself.
