The most successful group of the 50’s was the Platters. Inducted into the Rock and Roll Hall of Fame in 1990, they were reluctantly signed by Mercury records in 1955 as part of a deal to sign the Penguins who had just scored big with “Earth Angel.” However, the Penguins never had another big hit while the Platters went on to have three #1 hits plus eighteen other singles that made the charts. Their first hit, “Only You,” was released by Federal Records in 1955 and is worth up to $300.00 as a single. Their 1957 album, “The Platters,” on Federal Records, featuring “Only You,” can sell for $1,000.00 today.
