Antique Cast Iron Steamer Trunk Coin Bank Original Patina with dial coin cover

I don't know much about antique banks, but the back and coin cover appear to be original and complete. The bank appears to have never been cleaned. I'm guessing it's early 1900s but I don't know for sure. Perhaps if you are a collector you will recognize the maker marks at the screw hole on the bottom that holds the top and bottom pieces together. Dimensions are 3.5" wide x 2.5" tall by 2" deep. Best of all, it's not been cleaned so it has what looks to be its original patina from over the years. ---- OBAYB
