In the second photo, we can see FERDINA … S AV, which puts it in the reign of one of the Ferdinands who was Holy Roman Emperor ( 1619-1637 or 1637-1657).
In the first photo, we can see A : G : Z : B : T ….. Maybe these are the first names of two rulers, for example Albrecht Georg and ???
Edit: I tried searching on some names, but did not come up with anything.
Another possibility is that this is just a continuation of Ferdinand's titles (obverse: FERDINAND R I S AV for Ferdinandvs Romanorum Imperator Semper August… reverse: A G Z B for Austriae, Germaniae et Bohemiae … ??)
Anyhow, these are some possible starting points.
