Anti-counterfeiting mark of US dollar banknotes

How to identify the authenticity of US dollars?

1. There are 7 kinds of banknotes in circulation: 1 USD , 2 USD, 5 USD, 10 USD, 20 USD, 50 USD and 100 USD. Therefore, in addition to the above seven kinds of US dollars in circulation, the others should be regarded as counterfeit banknotes.
2. Identify the English on the ticket. Some scammers target people who do not understand English and use cheap or scrap currency that is not freely convertible to the country. Therefore, even if you do not understand English, you must mechanically memorize some English letters on the US dollar bill. In addition to Arabic numerals, the face value of the ticket also has English numerals in uppercase, such as ONEDOLLAR, TWODOL–LARS and so on. If the notes do not have these letters or are printed with other letter combinations, they are definitely counterfeit.
3. Remember the avatars on the front and the backgrounds on the back. The front face of the 1-dollar coupon is Washington, the first president of the United States, and the back image is the capital “ONE” in the middle; the front of the 2-dollar coupon is Jefferson, and the back is the declaration of independence in 1776; the front of the 5-dollar coupon is Lincoln, and the back is the Lincoln Memorial. The front of the $10 coupon is Hamilton, the first U.S. Treasury Secretary, and the U.S. Treasury Department on the back; the $20 coupon features the seventh President Jackson on the front, and the White House on the back; the $50 coupon features Grant on the front and the U.S. Congress on the back; 100 The front of the US dollar coupon is Franklin, and the back is the Independence Church. Some criminals change small-denomination banknotes into large-denomination banknotes. If they do not pay attention to the face of the face and do not know the English numbers, it is easy to receive counterfeit banknotes by mistake.
4. Pay attention to the color of the back of the ticket. Since the U.S. Treasury Department was authorized to issue banknotes in 1863, the back was printed in green, so the U.S. dollar was called “green back”.
5. Identify some features of counterfeit banknotes before 1996 with the naked eye. If the paper is soft, there is no crisp sound when it shakes up and down, the color is dark or yellow, the ink is too waxy, the face of the banknote is too smooth, the pattern is blurred, and the portrait has no three-dimensional effect, it is very likely to be a counterfeit banknote.
6. Identify the features of counterfeit banknotes issued after 1996 with the naked eye. After 1996, the printing process of US dollar banknotes has been further improved, adding distinguishable marks. The most notable thing is that the lower case numbers (5, 10, 20, 50, 100) in the lower right corner are discolored, appearing green when viewed head-on. If the lower right corner is slowly bent upwards, it will become brown-gray. If it does not change color, can be identified as counterfeit. Another important feature is the watermark on the front, and the watermark on the head of the real banknote is clear and clear. If it is not clear or the outline is not clear, it is very likely to be a counterfeit note.
7. If the amount of cash is large and the number of sheets is large, pay attention to the face number. Because in many cases counterfeit banknotes are double-numbered, if two numbers are found to be the same, it is certain to be counterfeit banknotes.
