1 Kreuzer 1780 Joseph II

I own a coin having the mint mark S and I haven't found it in among those listed. Also I am curious what is it about all those variants with "B" and "B." If needed I can upload a picture of the coin but it can be easily found on the internet with a simple search of "1 kreuzer 1780 joseph II" and the S mark can be seen.

I searched 1 Kreuzer 1780 Joseph II this came up on top

​Could you precise which coin you are talking about for the variants ?
Thanks, André

I see I overlooked that one, thanks Idolenz. And about the variants, I was talking about the ones produced between 1780 and 1790 but I researched a little more and I see there are truly 2 different mint marks, B and B with a dot. Sorry for my mistake folks.
