Seventy years ago today, on March 1, 1955 (February 8, 1955), the reason for the issuance of three-yuan banknotes was revealed. Since March 1, 1955, the People's Bank of China has started issuing new RMB all over the country, and at the same time recovering old RMB. Now, the People's Bank of China has shipped the new RMB to its branches in cities and villages all over the country. In addition to the original 19,000-odd units, the local People's Bank of China has entrusted some supply and marketing cooperatives, credit unions and state-owned enterprises to handle the exchange. In remote rural areas without banks and exchange agencies, the bank will send mobile exchange teams. Most of the personnel handling the exchange work have undergone short-term training and are familiar with the exchange procedures. In the past few days, in accordance with the provisions of the State Council's order on the issuance of new RMB and the withdrawal of existing RMB, the local people's banks have converted all the old coins deposited, saved, and lent in their account books into new coins according to the legal ratio of one to ten thousand of the old and new coins, and converted the old coins into new coins to the depositors of public and private enterprises, state organs, organizations, or cities who use checks. The work of changing the accounts of private enterprises in various places is also being carried out intensely. Since March 1, the new RMB has become the only unit of calculation for all currency receipts and payments, transaction valuation, contracts, contracts, documents, vouchers, account records, and international clearing in our country society. The second set of RMB issued with a face value of three yuan includes a very rare RMB - the dark RMB three, which is the only RMB banknote in our country with a denomination of three yuan. The overall color of the banknote is light green, 16 cm long and 7.2 cm wide. It is slightly larger than the 1 yuan in circulation today. There are traditional three yuan characters on both ends of the front. The bottom is marked "1953". The six characters "People's Bank of China" are directly above. In the middle is the picture of Longyuankou Stone Bridge in Jinggang Mountain. The lace around the stone bridge is dark green, and the middle is shaded in yellow. The back of the banknote is a pattern and the national emblem. In the middle is the words "People's Bank of China three yuan" in the four characters of Han, Wei, Mongolian and Tibetan. It was issued on March 1, 1955. Due to historical reasons, it stopped receiving and circulating on May 15, 1964 and was recycled. At present, there are very few in the world. The reason for the issuance of three yuan? The second set of RMB adopted the denomination of "three yuan" for two main reasons: First, because the Soviet ruble at that time was commonly used in the denomination of "three", with three kopi coins and three ruble banknotes. The second set of RMB began planning and design in 1950, and plate making and printing began in 1953. At that time, our country was learning from the Soviet Union in an all-round way, so it also learned from the ruble denomination system in this regard. The second reason is that time is tight and the capacity of the banknote printing factory is insufficient. At that time, our country's printing technology was still very backward, and the complex intaglio printing technology and watermarking papermaking technology used for large-denomination banknotes were not up to standard. Therefore, the large-denomination banknotes in the second version of the banknotes were entrusted to the Soviet side for printing, and the rest of the small-denomination banknotes were mostly provided by the Soviet side. The second set of RMB was originally designed with a maximum denomination of 100 yuan. Later, in order to prevent the Kuomintang who fled to Taiwan from counterfeiting in large quantities, the maximum denomination was limited to 10 yuan (so the cost and difficulty of counterfeiting were greatly increased). Under the condition that the total demand for money is determined, this greatly increases the printing workload. Even if the Soviet large-scale banknote printing factory has the capacity, it is very difficult to complete such large-scale production in more than a year. If there is no "three yuan" denomination, the printing volume of one-yuan and two-yuan banknotes will increase even more, and the printing task will be even more difficult to complete. Therefore, after technical discussions with the Soviet side, our country finally determined the denomination division of 1, 2, 3, 5 and 10 yuan to imitate the ruble. Because this denomination of RMB was printed in the Soviet Union at that time, and later due to the deterioration of Sino-Soviet relations, in order to prevent the Soviet Union from using the printing plate to print "genuine and counterfeit banknotes" and disrupt the financial order of our country, the People's Bank of China began to withdraw it within one month on April 14, 1964. On May 15, 1964, it stopped receiving and circulating.
