European medieval coin

[Gamlarkor]

Hello everyone
I would like to ask you to help me identify this coin.
It's probably silver (or billon) coin. 18 mm diameter and weight is under 1 g.

Hi Gamlakor, and welcome to WoC !

I am certainly no specialist on this category. But on medievel coins with crosses my first step usually is to classify the type of cross. Here it seems something between a "Jerusalem cross" and a "cross cercelee". I could not give you a direct attribution from that, but i would associate this primarily with medieval England ? Do you have any idea on the geographic origin of the piece ?
The other side is difficult. Is that a portrait of a crowned head facing right ?

Hope some of the other members can give you a more specific hint !

I'm pretty certain this isn't English coin of the realm. Whether it's some form of jeton/token from England I don't know.

maybe it is worth looking in this direction ...

Thank you all for your thoughs.
I was curious about your initial ideas before I post another info to assure myself I'm going right way.
Cross on the coin is probably moline cross with some kind of trefoil. Around trefoils and even around arms of the cross are some dots.
Based on the shape of cross I was thinking about some kind of medieval Austrian pfennig, because of the proximity to location, but the diameter of this coin is bigger. So maybe its good to look this way and maybe not. 
Then I saw that the same cross was used in medieval England coinage. I even heard that the coins with this type of cross could be produced for crusades (no written source for this, unfortunately).
I don't have an access to a catalogues right now so I thought that someone here can help me.

The other side is a bit tricky. Because its mixed with shapes from the "front". I have an idea how to make relief more visible, but i'ts litltle complicated. So first I want to know if we can get to something here with these pictures.
