I dont know how many types there are out there of your coin but what I can see is that the obverse design
of yours appears to be similar to the one from 1701 if you look at the alignment of the trees on the bottom.
However the tree that the wildman is holding looks like the 1699. The Skirt doesn't look like neither of them and if you look at the right forearm it looks very round.
The reverse looks like the 1699 but the stars are thicker and the lettering is slightly shifted.
The Stars in general look very off....
Although I would not worry about the rust spot I have found a couple of austrian silver kreuzer that exhibited the same kind of wear
