If it's a dime or quarter machine, load it up with old "real" silver coins and that should fix it. The old silver coins were a bit thinner than the newer (post 1964) fake coins. Newer quarters and dimes often (always?) pay out one coin short on the higher payouts due to the additional thickness of the coins. They just don't quite line up properly with the sliders due to the added thickness.
