I just came across this coin and would like to know more about it and what it might be worth. It has "1 Centner Kohlen' on one side and "Armenpflege Furth" on the other with a shield with a crown on top and a shamrock on it. It appears to be brass - about the size of a quarter.
I have no idea what kind of exonumia you have found (it's not strictly a "coin" as it lacks date, denomination, and country of issue), but this E-bay sale closed yesterday - actually there were two items and both went to the same buyer - so an inquiry to either of them through E-bay should get you an answer, which I hope you will then post here for the edification of all of us.
Was wondering if anyone ever learned any more about these notgeld tokens. Any recollection of what the realization on eBay was? I realize it was 5 years ago......
