A coin-freed mechanism for a vending machine has electrical sensing means (7, 9, 16) which are actuated to free the mechanism by relying on the electrical conductivity of an inserted coin (24) or a series combination of inserted coins (24, 25) of the correct denomination(s); the inserted coins themselves "make" or energize an electrical circuit which causes the normally-locked mechanism to be freed and goods to be dispensed from the machine.
