Based on list of titles that's Ferdinand the Second of Austria. Who had ND thalers.
N#424895
N#99227
Color does not look right. Based on his other coins in Numista he was following gulden weight in his large silver coins. If weight on first thaler page is correct, then it is gulden and not HRE standard Reichsthaler.
I assume you need “Die Münzstätte Hall in Tirol, Band 1. 1477 - 1665” for reference and finding matching lettering and mint mark.
