In ancient times, the paper used to make banknotes was generally leather paper used in Sichuan, and the production process was very complicated. At that time, it was particularly difficult to forge, and people were forbidden to buy it. Then other dynasties also had their own special paper to make silver tickets to prevent others from forging them.
The patterns on ancient silver tickets are also very complicated, usually very delicate. They are carved by hand with famous paintings. Carved patterns are varied, including houses, flowers and birds, figures and so on. Moreover, because these patterns are too complicated, they are all hand-carved, and it is difficult for counterfeiters to imitate them.
In the Qing Dynasty, the imperial court even set up a set of encryption technology for anti-counterfeiting. In this encryption technology, there is no mistake after birth. Therefore, the plot of robbing the silver ticket on TV series did not really appear in history, because both the official silver ticket and some private banks have some encryption and exchange certificates.
The crime of forging silver tickets in every dynasty was very serious, from exile to beheading and hanging, so the ancients dared not write anything on it.
