A saving stamp vending machine called the Automatic Receiving Teller made by American Banking Machine Corp. of Saginaw Mich. Made from 1910 to 1919.The front looks like a classic bank building and has insertion slots for pennies, nickels, dimes and quarters. Place a coin in the slot, push in the plunger and it would dispense a stamp in that denomination. The stamps would then be placed in a book and when the book was full it could be exchanged for a savings bond. Each coin slot has a reel type mechanism to hold a roll of stamps. The coins were stored in steel tubes behind the locked front panel. Machine is in good condition with light surface rust in spots. Comes with original lock and key. Overall measures 13" wide, 6" deep, 13.5" tall.
