Vintage Metal Coin Add O Bank

This little coin bank counts quarters, nickels and dimes. Insert the coin into the slot, slide the lever, save your money! It says State Securities Lincoln, Nebraska on the top, and American Industrial Bankers Association Member around the logo. The bottom says Add O Bank and has basic instructions on how to use it. The bank currently reads $3.85. I do not know how to reset it. The lock on the bottom is broken but the door stays closed. Inside the bank, there are two keys and what looks like part of a lock mechanism. I'm not sure if they all belong to this bank, but they will be included. The bank does have rust (see photos) and could possibly use a deeper clean. Vintage. Bank. Coin. Coins. Piggy Bank. Children's Bank. Money Saver. 1940s. WWII.
