Not at all. Compare closely the Works mintmark (second pic down in the list of mintmarks) with the Yunnan mintmark (fourth pic down). You can see slight differences. Count the strokes between the O-shaped letter and the final A-shaped letter; there's two on Works coins, only one on Yunnan coins. This is a Yunnan coin.
I suspect you're being thrown off by what appears to be a mark "underneath" the word, at 3 o'clock on the reverse. I think the bright spot there is not really part of the word, it's just a place where the black patina has been knocked off, exposing shiny metal underneath.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
