850-count gumballs are normally standard for vending in commercial gumball vending machines. It is customary to see them in most machines already in service. In earlier days, society was less accepting of chewing gum, so the pieces available for sale were smaller. As our population has become more accepting of gum chewing, and people's mouths have gotten bigger, a 1" gumball (or several) is considered an acceptable amount to chew at one time. With 850 gumballs in a case, each case has potential for $212.50 in revenue at 25¢ each.
