None of those coin-operated TV locations ever had UHF tuning available, most likely. They would have got their signals from an on-site MATV ("micro-cable-tv") installation that probably used cables that were not much good at UHF frequencies. At best, there would have been a few channel converters to change the local UHF stations to unused VHF channels, as is or was done on analog cable-TV systems in general. The same kind of setups you would see in hospitals, hotels, etc. before they started getting connected to city cable-TV systems.
