Celestia, The Nation of Celestial Space is based in Evergreen Park, Ilinois, USA. Founded by James Thomas Mangan, the Prime Minister, who laid claim to all space on January 18, 1949. Chartered on December 20, 1948. There are two well known coins of Celestia. First one is called Joule which is 4.1500g 0.9250 Ag with 19mm diameter coin dated 1961. Other coin is called Celeston which is 2.2000g 0.9000Au and minted from 1959 to1961. Both coins featured Princess Ruth Marie Mangan portrait. Beside this a few weak strikes of Celeston coin have also been minted in copper with 14mm diameter during 1959 to 1960.

The coin shown in the picture is dated 1960 struck in 0.900 fine gold by James Thomas Mangan. The obverse shows Ruth Mangan, James Mangan's daughter with "MAGNANIMITY" on the head band. Initially sold for $6.50 each, but the price was later raised to $10 each. See "Numismatic Scrapbook" Feb 1960, page 571 and "The Numismatist" Dec 2001 for more information. These coins are also unknown as UFO pocket change.

On December 20, 1948, James Thomas Mangan (of Evergreen Park, Illinois) gave birth to Celestia, “claiming all space in the sky as its sovereign territory”, in part because “we all travel through the sky 1,500,000 miles each day; and we are basically sky people — not earth people.” Mangan laid claim to on behalf of humanity to ensure that no one country might establish a political hegemony there. As Founder and First Representative, he registered this acquisition (the only one of its kind in all of history) with the Recorder of Deeds and Titles of Cook County on Jan. 1, 1949. At its foundation Celestia claimed to have 19 members, among them Mangan's daughter Ruth. A 28-page December 1958 booklet entitled “State of the Sky; Second Report to the Universe” chronicles the entire history of this entity up until its 10th anniversary. At that point in time, they had 19,057 participants according to their census, a far cry from the 19 with which they started. These “persons of unassailable magnanimity” indomitably cling to their thesis: “A wholesome search of the human heart reveals the time-heavy longing of all men for a country clean & free of the world's pressures & poisons.”
During its earliest years, Celestia “formally and repeatedly informed the State Department of every established Nation on earth of its existence, its claims, its rights, its intentions, its nationhood.” Their first Map was drawn in 1956 at a scale in which one-tenthousandth of an inch equalled 250,000,000 light years. In 1957, the U.S. Patent Office certified the name Celestia, making it the sky's legal designation.
Because Celestia completely “owns all space”, they peacefully protested several uses/abuses of the starry firmament as violations of their sovereignty. In 1949, they notified the United States, Soviet Union, United Kingdom and the United Nations that Celestia had “ruled against all further atom explosions (atmospheric nuclear tests)”. Their charter publicly forbade the use of the regions beyond our atmosphere to any artificial object/activity (this would come to include radio and television broadcast signals) without permission. However, the U.S. was the only nation for which this ban was lifted. In 1957, it was “granted a special license to send up man-made satellites”. It was also given exclusive authorization to make the first expedition to the Moon. But despite Celestia's strenuous objections to Andrei Gromyko (Foreign Minister) and Nikita Kruschev (who was warned by cable), the U.S.S.R. committed an act of trespass by launching Sputnik I. As a testament to his concerns over national security, Mr. Mangan in 1958 even “spent one hour and a half in spirited debate over the space claims” with the Second Secretary of the Russian Embassy in Washington, D.C. Later, as the space race got underway in earnest he sent angry letters of protest to the leaders of the Soviet Union and United States on the occasions that their early space flights encroached upon his "territory" - although he later waived these proscriptions to allow for satellite launches by the latter. While Mangan and Celestia were politely ignored by the superpowers, there is evidence that at least some others were prepared to entertain his claims with a greater level of seriousness.
On behalf of his heavenly cause, he toiled with “inflexible perseverance”, lobbying and petitioning higher-ups in all levels and branches of the government (Senators, Congressmen, Committees, the Pentagon, the President, the FCC, etc...). But in his quest, he remained a pro-American patriot who stood “ready to turn his claim to all space over to the United States of America.” As Head of State, he would make “an outright gift” of Celestia if it were to be used for national defense. The first unfurling of the Celestian flag - featuring a blue hatch symbol within a white disc against a blue field - was broadcast in June 1958 to a television audience of millions across the US. The next day, in front of the U.N. Building in New York City, it was flown alongside all the flags of its member nations. In July of that year, they “issued a Proclamation to the World, declaring the Moon, Mars, and her Two Moons, and the Planet Venus protectorates” of the Nation of Celestial Space. Mr. Mangan did so specifically to safeguard these bodies against unsanctioned “rocket shots” intended for them. Individual copies were conveyed to all the countries belonging to the United Nations. Despite these efforts, the Nation of Celestial Space is thought to have become defunct with the death of its founder. Its only surviving legacy is the series of solid gold and silver coins and stamps issued in its name by Mangan from the late 1950s through to the mid 1960s.

I have seen a good place to look for Celestia coins is Mike Locke's Web-site, a portion of which is devoted to gold coins he has for sale at  http://www.calgoldcoin.com/default.htm They also contrived some Ergs of Celestia Energy stamps.
I purchased my 1 Gold Celeston 1960 Princess Ruth Marie Mangan coin from John McCaugherty (Distinctive Coins / 422 W. 75th St. Downers Grove, IL 60516, USA / +1 630 968 7700). This coin is also listed as BR-X2 in Bruce's Unusual Coins.
