Every philatelist knows: the rarer a stamp is, the more likely it is to be worth a lot.
And if the postage stamp is presented in a single copy, then we may be talking about a sum of several million dollars.
An example of such an expensive brand is "British Guiana".
This sign, issued a century and a half ago, was sold for... 9.5 million dollars.
That is why this unique postage stamp received interesting “nicknames”: “Princess of Philately” and “Mona Lisa in the world of stamps”.
The sign was printed in 1856. There were two more stamps in the series. But their face value was 4 cents.
But the "British Guiana" was distinguished by its 1 cent denomination, which made this postage stamp unique.
The stamp has an octagonal shape. There is a picture on the sign - a three-masted schooner.
The unique stamp was first noticed by a schoolboy from Scotland. This happened in 1873.
The boy did not find the postage stamp in the catalogue and immediately sold the find to a collector for a small sum (literally 1-2 dollars).
Over the years, the value of the stamp increased. In the late 1870s, the sign was sold for $750, and in 1922, for $36,000.
In 2014, the British Guiana postage stamp was sold at auction in the United States. The unique item was purchased for $9.5 million. There are no more expensive stamps. However, it is possible that the record will be broken someday.
