Like many of you, during this coin shortage I am losing most of my quarters to the street. We have a three bay wash with three vacuums and a D/M vending machine. The wash bays use Sensortron coin validators that have the gauge coin installed in the mechanism. One vacuum uses Microcoin QL and the other two use MA-800 Multi Xeptor coin validators. The vacuums can be reprogrammed to accept whatever your drop through it, I would be limited to only tokens in the Sensortrons in the wash bays. I have seen posts where you blend quarters with tokens and I don't understand the benefit of that - I would like to set the pulses so one token equals 50 cents so I am not losing monies in the event someone drives off with the 30 cent tokens. Please share you thoughts, pros/cons, success/failure using the tokens.
