Hello and welcome.
Unfortunately, your coin is not a genuine Chinese tael. It is a replica. Compare your coin with the examples of the two varieties of this coin
here on zeno.ru. The dragons are very weakly struck compared to genuine coins, and the central Manchu inscription is incorrect; I assume the copy was made by someone who could proofread English and Chinese, but not Manchu.
The original tael coins were not struck in China; they were struck in European mints as samples and demonstrations, in the hope of winning coinage contracts from the Chinese government. In the end, China opted to issue dollars, instead of taels; circulating tael coinage is only known from a couple of western provinces.
