China 20 Fen 1909-11, Guangxu

Hard to be sure from the pics, but this example looks to be OK, style varied a little.
For genuine coins, fineness varied a little, at around 0.82 and bit lower, weight also varied a little at around 5.3 grams, and a little lighter.

There has been a recent boom in demand for genuine Chinese silver, and in the near future, I would expect there will be many more fakes being available, some good quality silver.
