In October of 1972 Michael Jackson made a rat a star when he hit #1 on the Billboard Hot 100 with “Ben.” It was his third time in Billboard’s top spot. He was 13. The rat was a little younger. The album, released on Motown, featured two different covers. The version showing just Michael Jackson on the cover is worth up to $20.00. But a cover showing Michael and a rat can sell for $75.00 today.(Find the values for every record by Micheal Jackson in our “Record Appraisal Guide,” available in the left hand column.)
