Two pence for the rest of the island

Mauritius set standardized inland postage rates in 1846 under Ordinance No. 13: one penny for delivery within town and two pence for other localities. To pay them, the colony issued two stamps on September 21, 1847, a one penny in orange-red and a two pence in deep blue. They were the first stamps authorized by any British colonial government.

Both were engraved by Joseph Osmond Barnard on one small copper plate, with a single engraving of each value, and 500 of each were printed by the intaglio method. The designs copied the British stamps of the day, with Queen Victoria in profile. Barnard's initials "JB" appear at the lower right of the bust.

The left panel reads "POST OFFICE." The next printing, in 1848, changed the words to "POST PAID," which is why the 1847 stamps are known as the Post Office Mauritius. The blue two pence became the stamp collectors called the "Blue Mauritius," the name Helen Morgan used for her 2006 history of the issue.

The engraver, and a story that was never true

Barnard was born in 1816 into a Jewish family in Portsmouth, England, and reached Mauritius in 1838 as a stowaway, put ashore from a ship bound for Sydney. Mauritius Post describes him as a jeweler. He was 31 when he engraved the stamps.

In 1928 Georges Brunel wrote that the words "POST OFFICE" were an error, and the story grew into a tale of a half-blind old watchmaker who forgot the wording until he passed a post office sign. Scholars have found no basis for it. Handstamps used on Mauritian letters before 1847 already read "Post Office," Mauritius Post says the wording copied a date stamp in use since the 1820s, and the first United States stamps of July 1847 used the same words.

A king's stamp

No collector knew of the Post Office stamps until 1864, when Mme. Borchard, wife of a Bordeaux merchant, found examples of both values in her husband's business correspondence. Prices climbed quickly: by 1897 only 17 Post Office stamps were known, and two of them sold that year for £1,860. Philipp von Ferrary owned six by 1893. The Independent's review of Blue Mauritius recounts a collector with 12,544 lesser stamps who announced in an 1891 lonely hearts advertisement that he would marry only a woman who owned one.

In 1904 an unused two pence was knocked down at auction in London for £1,450 to a buyer acting for the Prince of Wales, the future King George V, then a world record for a stamp. A secretary reportedly remarked the next day that "some damned fool" had paid a fortune for one stamp; George answered, "I am that damned fool." Helen Morgan's census describes this copy, with its large margins, as the finest known example. It remains in the Royal Collection.

Another unused two pence descended through the great collections. It was found by Mme. Borchard, bought with an unused one penny by Henry Duveen in 1909 and by Arthur Hind in 1923, the pair for about $30,000, and acquired by the collector Hiroyuki Kanai in 1965. When the Kanai Mauritius collection was sold at auction in Zurich in 1993, it brought 1,725,000 Swiss francs, reported as $1,148,850 with the 15 percent premium, slightly more than the unused one penny in the same sale. A consortium of Mauritian companies bought both.

The same 1993 sale included the Bordeaux cover, the only cover bearing one stamp of each value. Mailed on October 4, 1847, to the Bordeaux wine merchants Ducau et Lurguie and found in their papers by a student in 1902, it sold for a price reported as 5,750,000 and as 6,123,750 Swiss francs, $3,829,500 in one account and about $4 million in others.

The two pence that went into a mine

A second envelope from the same Bordeaux merchants carries a single two pence, with a piece torn from the left side near the "O" of "OFFICE." A French student found it among the merchants' papers as well. It sold in 1903 for £1,200 and was resold the same year for £1,400, and in 1904 the postal museum in Berlin acquired it, displaying it in a glass wall frame with seven other stamps.

In 1943 the frame was stored in the Reichsbank in Berlin to protect it from bombing, then hidden in a potassium mine near Eisleben. After the war it came into the hands of an American captain, Dennis Sweeney, who tried to sell it through a stamp dealer; the dealer alerted Interpol and Germany claimed it. Sweeney handed it to a U.S. customs agent in 1977, and in 1990 the frame was returned to a reunified Germany and shown in Bonn.

Two pence Post Office stamps can be seen today in several public collections: the Museum for Communication in Berlin, the Museum for Communication in The Hague, the Postal Museum in Stockholm, the British Library in London, and in Port Louis, where the Blue Penny Museum shows the unused Kanai two pence and one penny bought in 1993 by a consortium of Mauritian companies, reported as $2 million for the two. To protect them, the originals there are lit only for short periods.

Counting the blues

The two pence is deep blue, imperforate, with Queen Victoria facing left and "POST OFFICE" down the left side. The shading dots in the portrait gave the queen what one reviewer called the look of smallpox. The stamps have been reprinted from the original plate and forged many times, so a genuine example is identified against the recorded census.

Sources give different counts. Hiroyuki Kanai's 1981 book Classic Mauritius puts the total of both values at 27, and the census compiled for Helen Morgan's research companion lists 12 two-pence examples, four unused and eight used. A summary published with a stage play about the stamps says three unused are known, and Mauritius Post's museum page says only 12 Post Office stamps of both values remain. A used two pence sold at auction in London in 2011 for about £1 million. The Independent noted that the blue two pence is even more coveted than the red penny.

A realized auction price is what a buyer actually paid on the date shown, including the buyer's premium where the sale reported it. It is the strongest kind of reference price, and it is a record of one sale of one object on one day, not a promise of what the next example will bring.

By reference price, Mauritius 'Post Office' 2d Twopence is number 15 of 100 in the stamps entries of the FLOAT 100. 82 of those 100 rest on a realized sale; the rest carry an asking price or a guide value, and each page says which. Rank within the FLOAT 100 itself (4 here) is editorial: how much an object defines its field, not price alone.
