Abstract: A coin mechanism for use with a vending machine where there is a coin barrel that receives the particular coins inserted vertically downwardly by the customer into a coin receiver. The coin barrel has an outer position where the coins can be inserted into the coin receiver and an inner position where the coins are checked by a coin discriminating mechanism, and, if proper, will allow the coin barrel to be rotated further by the customer to activate the vending machine to release the particular selected product. In the even the customer has made a mistake or has had a change of mind, the coin barrel is also allowed to be rotated by the customer, when in its outer position, to a position where the coin receiver is facing substantially downwardly so that the coins can be readily retrieved by the customer and are allowed to fall downwardly by the force of gravity.
