VAULT READY DESCRIPTION: There are two primary ways to store coins in a self-serve environment; either inside the equipment in a coin box or in a vault that is installed beneath the meter to collect coins. Vaults can hold anywhere from $700 in quarters for the 10-inch model up to $1600 for the 18-inch (10”, 14”, and 18” vaults available for sale). Since most vaults are cemented or bricked in on all sides they are very difficult for thieves to break into.
