These are typically referred to as "Black Bats" and have been produced by batmaker Hillerich & Bradsy (makers of the "Louisville Slugger") to honor each season's American and National Legaue champions since 1934. They were made in relatively large quantities and presented to players and team personel, as well as league officials and VIPs. Ironically, bats made in the last ten years are worth more than those produced decades ago, as H&B cut down the quantities distributed significantly in the early 90's due to the expense. Yours is one of the better bats and its value is truly a function of its overall condition, with a safe appraisal being $400-750. Bats surviving in Near Mint condition would warrant the top value and possibly more.
