Identifying Middle Age German Coin

Hello Numista Community,

I could use some help identifying this coin. What do you think?

German brass token, probably from Prussia 1750-1850 ca.

Reverse lettering: HEILIG KREUZ
Translation: Holy Cross
Can't read obverse lettering, but at 1 o'clock is visible "...MA...".

Your token is similar to these:
