Silesia Ferdinand ?

Partially because most of the date is off the flan, I have been unable to attribute this 3 kreuzers. Can anyone assist?

The coin is 18mm and weighs 0.7 gram. There is a 2 at the top of the reverse, which appears to be the end of the date.

The obverse legend appears to begin FER.D.G...
The reverse legend begins MO.NO.AR (3) GE.SILES

I think it could be Ferdinand II
FERdinandus Dei Gratia Hungariae....  ?

KM# 39 ?
1622  ?

Maybe. The reverse is similar to that type.

The description of the obverse is that it is an orb; this is a portrait.

Yes you are correct. I went too fast.
The 2 that you say is from the date, can well be a Tironian logogram Z.

I still am searching for you coin, it intreges me!!

FER D G R I ....?
Ferdinandus Dei Gratia Romanorum Imperator .... ?

The weight and diameter looks more like '1 kreuzer'

I thought I would finally get to use the Austrian coin book I bought several years ago, but I found that it only covers 1740-1969!
