Hello everyone, I just got my very first metal detector!!! My third day in I was in a construction zone near hospital and beach and found a trade token I am doing research on and saw a few similar coins on this site and thought maybe someone could help me. Not sure how to use site nor if im sending message to a post wall or what. Anyway, I found a J.M Brunswick and Balke Co trade token and on other side says Berken Bros. Coin is in Very good shape. Brunswick emailed me back it was used from 1874 to 1884 but not sure where or who Berken Bros. are. Any info would help. Thank you and Happy Hunting!
