16?6 Kreuzer? | Austria 1626

I have this coin that is very worn down and very thin.
It's date appears to read 1686 but the 8 is a little too worn down to be sure if that's it.
I have done research on this coin before finding that it might be an Austrian Kreuzer.
But its been awhile and I cant find the exact coin online anymore and was wondering if any of you guys have any other ideas.
The date is printed below the head and there is what I'm assuming is the roman numeral I under the date in a circle.
The lettering around the head appears to read S A G (H or N) E B R E F G R [starts to get very thin and unreadable but goes on for about 5 characters]
That might be completely incorrect but that's what I can read off it.
