Collectors offer a fortune for a given dollar bill. I know how they are and why they want them.
A total of 6.4 million two-copy banknotes were issued in the United States and there are many groups that would be willing to pay up to $150,000 for a copy. Just like the $100 denomination that sells for over $26,000.
The state agency responsible for printing US dollars is the Bureau of Engraving and Printing. In 2014, they mistakenly issued two identical $6.4 million notes. The first was distributed in New York, while another, exactly the same, arrived in Washington two years later.
In this way, it means that there are twin fiat currencies because they both have the same serial number and are spread around the world. So far, only 9 copies of these pairs have been found and some collectors offer a fortune to keep.
How do you distinguish them from the rest??
Your ID must be between serial numbers B00000001 and B00250000, or between serial numbers B03200001 and B09600000, in the same year 2013. Also, the paper must have the Federal Reserve stamp on it with the letter “B” and the serial number must end with an image of a star.
