First of all, it was because at that time, the ruble of the Soviet Union often used "three" denominations, including coins of three kopecks and banknotes of three rubles. The planning and design of the second set of RMB began on 1950, and plate making and printing began on 1953. At that time, China was learning from the Soviet Union in an all-round way, so it also learned from the ruble denomination system in this respect.

The second reason is that time is short and the capacity of the banknote printing factory is insufficient. At that time, China's printing technology was still very backward, and it was not enough to master the complex gravure printing technology and watermark papermaking technology of large denomination banknotes. Therefore, the large denomination banknotes in the second edition of currency were entrusted to the Soviet side for printing, and the paper of the remaining small denomination banknotes was mostly provided by the Soviet side. Initially, the maximum denomination of the second set of RMB banknotes was 100 yuan. Later, in order to prevent the Kuomintang fleeing to Taiwan Province Province from forging in large quantities, the maximum denomination was limited to 10 yuan (which greatly increased the cost and difficulty of counterfeiting). When the total demand for money is determined, this greatly increases the workload of printing. Even the production capacity of the large-scale banknote printing factory in the Soviet Union is difficult to complete such large-scale production in more than a year. If there is no "ternary" denomination, the printing quantity of one-yuan and two-yuan banknotes will increase even more, and the printing task will be more difficult to complete. Therefore, after technical discussions with the Soviet side, China finally determined the denomination division of 1, 2, 3, 5 and 10 yuan to imitate rubles.

Because 3 yuan banknotes have stopped circulating for nearly 60 years, and most of 3 yuan banknotes were recycled by banks in those years, people's awareness of collection was not strong at that time, and some 3 yuan banknotes that are often seen in the general market are mostly old banknotes that have been pasted and repaired, and their collection value is greatly reduced.

At present, the market price depends on the quality, generally around 3000 ~ 30000 yuan.
