Custom Fidelity Series

This short lived series (1954-1957) contains a mere 6 albums of soloist and small ensemble recordings. As was the case with the MG-40000 series, Mercury deleted the series from their catalog at the beginning of 1957 and incorporated it into the MG-50000 series by re-cataloging MG-80000 through MG-80004 as MG-50089 through MG-50094, skipping MG-50093.
