There are many ways to write "er" in traditional Chinese characters and various calligraphy, and this way of writing is one of them. It has existed since ancient times. In the early days, RMB was often written like this. It was not until the 1980s that the country introduced a standardized simplified Chinese character scheme, which unified the writing of "er". Therefore, since the fourth set of RMB created by 1980, the writing of "two" has been unified to the present appearance. Prior to this, all kinds of currencies produced by plate making were not wrong editions, and the state did not recycle them specifically.
1962 2 horn is a common variety in the third set of RMB, which is divided into three versions: intaglio, lithography 3 crown and lithography 2 crown. At present, the market prices of brand-new products are around 30 yuan, 5 yuan and 4.5 yuan.
