If you have a small stamp showing a plain numeral and the word Hawaii, and you have just read that one of them sold for two million dollars, this page is going to save you a week. Hawaiian Missionary stamps are among the rarest issues in the American collecting world, and also among the most reproduced, which means the odds facing the copy in your hand are unusually easy to state and unusually one-sided.

Hawaiian Missionary stamps are the first issues of the Kingdom of Hawaii, placed on sale on 1 October 1851 in 2, 5 and 13 cent values, joined in 1852 by a fourth stamp, a redesigned 13-cent. There were only ever three Missionary denominations. About 197 examples are recorded, only 15 of them the 2-cent. Almost every copy in private hands today is the 2002 United States 37-cent commemorative sheet.

The interesting question, then, is not what a Missionary is worth. It is which object you are actually holding, and that turns out to be answerable in about ten seconds without any expertise at all.

What are Hawaiian Missionary stamps?

In 1851 the Kingdom of Hawaii was an independent monarchy with a mail service and no stamps. The Honolulu post office solved that with the tools it had: a jobbing printer, a case of loose metal type, and thin, fragile paper. The result was four small stamps carrying almost nothing but a numeral and lettering, with no portrait and no engraving. They acquired the name Missionaries because so much of the surviving correspondence was sent by American missionaries working in the islands, whose letters home are why any of them exist at all.

The whole issue is smaller than a single day’s print run of an ordinary modern stamp. Scott Trepel’s census in the Siegel catalogue lists 197 recorded examples across the four stamps, of which 28 are unused and 32 are on cover, meaning still attached to their original envelopes. Both the census figure and the survivor arithmetic behind it are the kind of hard, checkable rarity described in what makes a stamp valuable, and they are the reason these stamps sit alongside the legends in the rarest stamps in the world.

Why is the 2-cent the rarest of them all?

Because of what it was for. The 2-cent value paid postage on newspapers and printed circulars, which travelled in flimsy wrappers that nobody had any reason to keep. The 5-cent and 13-cent values paid letter rates, and letters get saved in bundles, in drawers, in family papers. Wrappers went in the fire.

The result is that 15 copies of the 2-cent are recorded, and exactly one of those is unused. There is also exactly one surviving envelope carrying a 2-cent Missionary, known as the Dawson cover, which also carries a 5-cent Missionary and two United States 3-cent stamps. Its own survival is close to accidental: the auctioneer Scott R. Trepel told UPI in 1995 that the envelope had been retrieved in 1905 from a furnace in which old records were being burned.

What have Hawaiian Missionary stamps actually sold for?

Two figures from a single week in November 1995 remain the clearest benchmarks, because they were reported contemporaneously rather than repeated second hand. At the dispersal of the Honolulu Advertiser Collection in New York, UPI reported that the Dawson cover sold for $2.09 million to the Swiss collector Guido Craveri, then the highest price ever paid at auction for an American philatelic item, and that an unused 2-cent Missionary sold for $660,000, then a record for a single United States-related stamp. The Smithsonian’s National Postal Museum was outbid on both but acquired other Missionary material from the same sale, including a used 2-cent and a strip of three 13-cent stamps on cover.

That unused 2-cent has a second life in popular culture. It had sold for $41,000 in the early 1960s and appeared in the 1963 film Charade, at which point Life magazine calculated its value per pound at roughly $1.2 billion, the stamp weighing about one two-hundredth of an ounce. Later sales of the Dawson cover have been reported at higher figures, but published accounts differ on the exact numbers, so the 1995 results are the ones worth quoting.

The murder story, told honestly

Every article about these stamps tells the same tale: that in 1892 a Parisian collector named Gaston Leroux was murdered by a fellow philatelist, Hector Giroux, who coveted his 2-cent Missionary and confessed under police questioning once the stamp was missed from Leroux’s inventory.

It is a very good story and it should be labelled as what it is. Searching for the primary sources a real 1892 Paris murder trial would have generated, court records or press reports naming both men, turns up nothing but philatelic retellings of the same anecdote, and the retellings do not agree with each other on how Giroux was caught. Treat it as folklore that has been attached to the stamp for over a century, entertaining and unverified. The documented history is dramatic enough without it.

What is documented, and stranger, is the Grinnell affair. In 1919 or 1920, depending on which account you follow, a Los Angeles schoolteacher named George Grinnell produced 43 Missionaries at once, more than a fifth of everything then known. A court adjudged them forgeries in 1922. A group of them went to the Royal Philatelic Society London’s expert committee in November 1951, and that body reached the same verdict two months later, yet analyses of their ink and paper have continued to divide specialists ever since. A century on, the Grinnells are still argued about, which tells you how hard authentication on this issue really is.

Could I have one?

Almost certainly not, and the reason is cheerful rather than deflating: the thing most people own has a known identity. In 2002 the United States Postal Service issued a $1.48 souvenir sheet of four 37-cent stamps, Scott 3694, reproducing Hawaii’s first four stamps and printed over a photograph of the Dawson cover itself. Mystic Stamp Company records a print quantity of 1,610,000 sheets and retails one at $5.95 (dealer retail), which is why it is the object most often mistaken for a Missionary: it went out through ordinary post offices in numbers the 1851 issue never approached.

Four checks settle almost every case, and none of them requires a catalogue:

  • Read the numeral. A 37 means 2002. No Hawaiian Missionary was ever issued in a 37-cent denomination; the genuine values are 2, 5 and 13 cents.
  • Count the stamps. The 2002 issue is a connected block of four different designs on a single sheet with a photographed envelope behind them. An original is a single small stamp with nothing behind it.
  • Look at the printing. The 2002 stamps are modern full-colour offset on bright, smooth paper with clean machine perforations. The originals were set in loose metal type and printed unevenly on thin, fragile paper that a strong light shines through.
  • Ask for the paperwork. With 197 recorded items, genuine examples are individually catalogued and change hands with certificates from expertising bodies such as the Philatelic Foundation. Nothing enters this market on the strength of a family story.

Nineteenth-century forgeries exist too, made when the stamps were already famous and already valuable, and some are good enough that specialists still disagree about them. That is the practical reason the certificate rule is absolute rather than fussy.

What to do with the stamp in your hand

Photograph it and find out what it is before you build any expectations on top of it. That is the same discipline that turns the other great American rarity into an answerable question rather than a fantasy: the census behind how many Inverted Jenny stamps exist accounts for all 100 examples individually, and the tier-by-tier figures on our Inverted Jenny page exist precisely because the population is known. The same check settles the other famous American headline, the Z grill stamp, where a quick look at the grill tells a common example apart from the legend.

The Hawaiian Missionaries are the same kind of story with a smaller cast. Ten seconds with the numeral tells you whether you are holding a $5.95 souvenir sheet or something that would need a certificate before anyone would discuss a price, and knowing which is worth far more than hoping. Photograph the stamp, let Stampo identify it, and spend the week you just saved on the rest of the album.
