Help cataloging this German coin?

Hello friends of the forum, I ask for your help in cataloging the following coin. The seller gives me the following information:

Weight: 0.53g

Attached are photos of the coin. 

Looks like a coin from Geneva, Switzerland, Swiss Cantons.

Not really … I'd really wish there was a nice comprehensive catalog of arms where you can select the type of shield and the elements.

N#191130

Well, Geneva looks a kind of similar…

But it is not this coin.

These two are also close:
N#92064

N#32206

Maybe my eyes are playing tricks, but my first impression was a rampant lion facing left on the left side of the shield.

No your eyes are well, it's a lion or panther or at least something rampant (I have seen one that was called a beaver [lion with a beaver tail]).

I can also find lions and keys for Bremen, but not in this configuration (yet).

Added:  Chur has a rampant ibex (or goat?) and was a bishopric, but again, no luck finding a coin with these two things combined like this.
