Need some help identifying a coin.

Hello,

I have a copper(I think) coin that is pretty old, so it is rusted and worn, but I can read the value which is "1 PF.", surrounded by dots around the edge. The other side has what appears to be a crest with an eagle on it, possibly German or Polish, surrounded by small beads, with stars circling that, but closer to the edge. Its old and worn, but weighs 1.5 grams, and 18.29 mm wide, if that helps.

If anyone has an idea of what this coin or token might be, please let me know. Here are a couple of pics:

This seems to be play money from Germany. Time 1873-1889
as it is the old crest.

there are some notgelds with a similar revers face :
Gerlingen (Württemberg)

Thank you both for your information. I really have no idea where I acquired it, but since I collect tokens also, this will be a neat addition to my collection. I really appreciate the help. Take care,

Ken
