The picture below shows a larger view of all (4) Different Old UnitedStates Military Insignia Gum Ball Machine Prize Toy Rings in this lot. These rings are not dated but they are from the 1960s. The rings have detailed and clear insignias. These were sold from gumball machines. Two of the rings are made of silver painted plastic and two have copper coated plastic. They are all unused and two (bottom ones pictured) are still on their original special plastic gumball machine section. These holders were specially developed and made for rings in gum ball machines to keep them from jamming the machine without using capsules. The toy rings in this lot are from the following UnitedStates branches of military service:
U.S. Navy U.S. Army U.S. Army Air Corps U.S. Marine Corps
To judge the sizes the red Marines ring top section measures about 1/2'' x 5/8''. These appear to be in mint unused condition as pictured.
