The picture shows a view of all (10) Old Car & Truck Gum Ball Machine Prize Charms in this lot. The two truck charms at the top are old two part gum ball machine prize charms. They look like either oil tankers or milktrucks. The other one at the top is metal and it had rolling wheels. In the next row the first one is copper coated. The second from the left is metal and flat. It most likely is from a charm bracelet. All others are plastic. These are believed to be from the 1930's to the 1960's. To judge the sizes the two part truck charms each measure 1-1/8" long. They range from very good to mint condition.
