Your question is not accurate. Money is divided into paper money and silver coins. As far as paper money is concerned, there are dozens. In addition, there are local and central government issues. The most typical is the legal tender issued by 1935, with the maximum face value of 100 yuan, but soon, the legal tender began to depreciate. The maximum denomination has been raised again and again, 1 1,000 yuan, 2,000 yuan and 5,000 yuan. . . Before 1948 stopped using legal tender, the maximum face value had reached several million. The gold certificate issued later is even more outrageous, with the highest denomination of hundreds of millions. Before 1935. Legally, silver dollar is the most important currency in circulation, and paper money is an auxiliary currency, so the quantity is small and the function is small, and the maximum face value is generally not more than 100 yuan. As for silver dollars, there are more kinds. The most famous is Yuan Datou, which has a large circulation and a long issuing time, and no silver coin can compare with it. Its year numbers are three, eight, nine and ten years of the Republic of China, and the number of eight years is relatively small. The maximum face value of a silver dollar is one yuan. In Yuan Datou, there are secondary coins such as China dollar (50 cents), 20 cents and 10 cents in only three years, and there are no figures for other years. Its influence is second only to that of Yuan Datou. On the front is the head of Sun Yat-sen with the year number on it, and on the back is a sailboat above the sea. Thirdly, Sun Yat-sen's founding commemorative coin is also called Xiaotou. As for other forms of commemorative coins, although there are many kinds of silver dollars and sample coins, the circulation is too small, and some have only issued hundreds or even dozens. Now, there are almost no genuine products on the market.
