Antique and vintage gumball machines can be found online at eBay.com and could also be available via private sellers and live auctions. The American Gumball Machine Company stocks both antique and new gumball machines.
In many cases, those selling the gumball machines do not have keys to the machine. Buyers can check with a locksmith who might be able to make a key for the machine. Vending machines made after World War II are considered the easiest for beginners to start collecting.
Both eBay and the American Gumball Machine Company have gumball machines in a variety of styles and from different eras.
