I am having trouble seeing your coin, is this it?
some marks may differ a little [date]
In 1905, the designs were changed, replacing the emperor's name with the Chinese characters for Da Qing ("Great Ching") and the two characters either side with Tong Bi ("bronze coin"). These new coins were in four different denominations, valued at 20, 10, 5 and 2 wen (cash) of standard bronze coins and weights of 0.4, 0.2, 0.1 and 0.04 of a tael. These Ta Ching coins, and those that followed, are slightly larger and thicker than the earlier milled coinage. They were first introduced by the Tianjin mint, now renamed as the General Mint of the Ministry of the Interior and Finance, with the reverse legend in English TAI-CHING-TI-KUO COPPER COIN and the emperor's name above in Chinese characters. Similar coins were produced in the provinces. Most bear two Chinese characters, one either side of the obverse denoting the date based on the ***agenary cycle. In the example illustrated below these characters appear in the 3 o'clock and 9 o'clock positions on the obverse and are equivalent to 1907. Coins produced other than in Tianjin usually bear a small mintmark character in the centre of the obverse on a raised circular disc.
yours looks to be [1907 -丁未] same as the one below.
