It is worth such huge money of the brand, of course, because of its limited circulation, and most importantly, because of the special impression-waxing. It was applied to its surface with a simple and practical purpose-to prevent the re-use of the postage stamp by washing off the ink of the stamp.
Already at the very beginning of issuing postage stamps, 'craftsmen' immediately invented a way to remove stamp traces from their smooth surface, using stamps twice or more times.
The phenomenon became so widespread that the US Post Office began to suffer losses. An employee of the American Banknote Company, Charles Steele, offered a way out. In 1867, he patented his invention, known today as waxing. A simple procedure is to apply a special impression on the stamp, after which a pressed impression appears on the back of the product in the form of a grid. This surface structure with micro-fractured fibers perfectly absorbs ink, and it is no longer possible to wash it off.
