"a look"
Look at the watermark: pick up the bill and point it at the light. Look at the white area on the left. There is a clear watermark of Chairman Mao's head.
Look at the word: below the white area, there is a word "100", which is green when viewed directly, and will turn gray when viewed from a certain angle.
Look at the red oval area in the upper right corner of the banknote: If the banknote is tilted at a certain angle, you can see the words "100" in the red area.
Look at the back: on the gold line on the back of the bill, the words 100 are written. Moreover, if the banknote is properly tilted around the gold thread, the steel seal of "100" will be found.
"second contact"
At Chairman Mao's collar, at the fold line in the lower right corner, you can clearly feel it protruding when you touch it with your hand.
"three listening"
Real money sounds crisp and pleasant, and its voice is rich in texture. Although counterfeit money sounds soft.
"Four major tests"
With the help of some simple tools and special instruments, the authenticity can be distinguished: if the face is irradiated with ultraviolet rays, the fluorescence reaction of banknote paper and ink can be observed; With the help of a magnifying glass, you can observe the details such as the clarity of the ticket line, glue, gravure characters and so on.
Look at the cut and paste marks.
Why should we pay attention to the cut and paste marks on the ticket face? Because this is a typical feature of "piecing together counterfeit money". Criminals cut and divide counterfeit money and real money separately, and then put them together, which will make counterfeit money also have some face characteristics of real money. If only the face value of the real money is checked during the appraisal, it is easy to receive it by mistake. In many collected "patchwork counterfeit money", the proportion of real money face is often greater than that of counterfeit money face, which further increases the deception of such counterfeit money.
So how to identify this suspicious coin? Firstly, the ticket face can be divided into several relatively complete areas according to the traces of cutting and pasting, and then the anti-counterfeiting characteristics of each area can be checked separately, so as to infer whether it is pasted by the real ticket face.
