Sorry but your pictures aren't showing up. As far as I'm concerned, "Tael" is a form of measurement used by the ancient (?) Chinese. I have read that "one" tael varied from providence to providence.
What you likely have is a silver sycee, denominated in taels. These are almost always fake and without the picture there is no way to tell.
do you have a picture because i also have that and other province coins. I know little about them right now but i do know somethings that might help if it is like mine
