Coinco Model S75-9800B coin changer. This was found in an estate so I do not know its history, however it was in a box with several other coin changers that had service tags. It may mean that this unit was repaired/serviced but then not put back into use, however I cannot confirm this.
It is untested as I do not have a method to test it. It was kept in an indoor temperature controlled closet all these years. Please enlarge and zoom in on all the pictures to view all the details of this item.
