In 1661, The young Shun Chih Emperor caught smallpox and passed away. His third son, Hsuan Yeh was chosen to succeed the throne at the age of eight with the reign title K'ang Hsi. The Emperor K'ang Hsi had reigned China for 61 years. His long and prosperous reign periods was famous not only of the Qing dynasty but of the whole of Chinese history. When he passed away in 1722, he left a flourshng and stable kingdom.
The coinage of the K'ang Hsi series is very interesting. Have you heard about the K'ang Hsi Ch'ien Shih ? It was arranged by the Chinese collector with the different mints in the form of a Chinese poetry during the Chien Long period and now it is the favourite target for the Chinese collectors.

I give below is an interesting belief wrote by Mr. Fr. Schjoth in 1929. I came across it in my reading a few weeks before.

The coinage of K'ang Hsi reign followed the forms of the last two issues of the Shun Chih coin. The obverse of the coins bearing with the reign title of the Emperor K'ang Hsi, along with the characters "T'ung Pao" in Chinese. The reverse of the coins, except those cast by the two principal mints in Peking, Kung-pu Pao Yuan Chu [Board of Works] and Hu-pu Pao Ch'uan Chu [Board of Revenue], all the provincial K'ang Hsi coins, show the mint mark in Manchu script [left] along with the mint mark [right] in Han script. The mint marks of the two principal mints were written in Manchu scripts only, appear on either side of the hole on the reverse. The forms are consistent until the beginning of the Yung Zheng coinage. But the number of the provincial mints was often changed. This was certainly caused by the increased or decreased work in connection with the cash production. In 1662, most of the provincial mints were terminated casting coins except Kiangsi Mint (Nanchang) and the two principal mints in Peking. It might be because of the over supply of the copper cash or the price of cash was too low at the beginning of K'ang Hsi reign.*

All the provincial mints were reopened in 1667. But I believe that a limited amount of K'ang Hsi T'ung Pao were possibly cast by the provinceial mints in 1661.
I have selected 25 pieces of K'ang Hsi T'ung Pao coin from my collection and divide them into 5 parts showing here. All the K'ang Hsi cash would be shown with a detailed description.

[The Official exchange rate of copper cash to silver was 1000 to 1 (1000 standard cash to 1 tael of silver). Actually, the changes in the cash-silver exchange rate were determined by the natural economic forces. Sometimes when the ingredients contained in a copper cash became more valuable than its face value, copper cash were melted down by the criminals in order to get the copper.]
