Yes, if the value of stamps is measured, people used to think that the magenta 1-cent stamp of British Guiana in 1856 was the most precious. It is an orphan of the world. When the international stamp exhibition was held, the ticket was included in the bulletproof glass safe, and visitors could only peek at it from a distance. In front of the safe, armed guards stood in awe, which made people feel the extraordinary value of small pieces of paper.

In fact, this is a little disfigured piece of paper. Its pattern-a sailboat-was taken from a local sailing news newspaper in Guyana, and a motto in the newspaper was also printed on the stamp: "We give and seek something in return." Before the birth of this stamp, British Guiana had been relying on London to supply stamps. Later, when the shipping schedule was delayed and the stamps were out of stock, the local post office printed the stamps itself, which may be the original intention of adopting the sailboat pattern. This stamp is postmarked "April 4th, De Manlalle" and signed by the postal staff. One-cent stamp is mainly used to post the news of the shipping date, so few people keep it. It was not until 1873 that a Guyanese student found it among the old letters and sold it to a postman at a price of 6 shillings. By 198, the world's first rare postal product had changed hands several times, and it was worth $85, in the auction market in new york.

in fact, there is a stamp that is more expensive than Guyana's one-cent stamp, that is, the American "Blue Boy" stamp in 1846. It is a temporary stamp issued by Brian, the postmaster of Alessandra, USA, for local use. The face value is 5 cents, and the pattern is a circle of roses, with the English letter "Alexandra Post Office" in it and the words "5 cents paid" in the middle. Because it is printed on blue paper with black ink, only one real envelope has been found so far, so stamp collectors love to call it "Blue Boy". In 1981, its realized price in the Geneva auction was $1 million, one point more than Guyana's.

In the final analysis, Jane Post has no "elegant demeanour", and most of its features are rough, which is far less exquisite and beautiful than "black penny", the originator of stamps. "priceless" is to a large extent praised, and it is created by thousands of super-rich people who are eager for it and are eager for it. Apart from some value in postal history, these rare stamps have little aesthetic value. International stamp collecting activities used to be a game of dignitaries for a long time, which was called "the entertainment of kings", and only those who spend a lot of money can get involved.
