The paper became so depreciated in value that in 1309 there was a fresh issue, made to replace that which was the discredited paper, but this also sank rapidly in value, and at length the Emperor, Khaissan, determined upon a recurrence to the ancient money, and accordingly, in 1310, there were struck two kinds of copper coins, having Mongol characters upon them. Some with the inscription, precious money of the Zhida period; and others with this legend, precious money of the Great Yuan. These copper coins were of three sizes: 1 of the value of one li; 2 of the value of ten li; and 3 of coins worth several of those of the dynasties Tang and Song dynasties. Khayishan's court encountered financial difficulties. For example, the total government expenditure for the year 1307 was 10 million ting of paper notes and 3 million dan of grains. By 1310, 10,603,100 ting had been borrowed from the reserves for current expenditures.
