1780 Thaler - But Precisely What Type?

Oh. Thanks for the link to the other thread (albeit I haven't gotten through all 26 pages of it yet). I hadn't realized there was such a comprehensive discussion already here, but I ought to have guessed as much. I do see that these dots and their significance are mentioned early on there. However, my #1 (the better struck specimen) does not have them. So exactly what does that indicate, if anything? Even if the dots do verify that a coin was struck at Vienna, it doesn't follow as a logical necessity that their absence means that a coin was struck elsewhere, even though that may be in fact what is the case.

Edit: I should add that I'm now wavering on my previous thought that #1 and #2 are of the same type, despite the coincidence of their weights and similarity in dimensions.
