How do you find the value of an old wooden bat made by JF Hillerich and Son?
If your bat reads J.F. HILLERERICH & SON in the center brand as you state It would be dated before 1916, and will be a very nice collectible. In 1916 Louisville Slugger started to use HILLERERICH & BRADSBY Co in their center brand. If it reads “Trade mark” below the oval as opposed to “TRADE MARK REG US PAT OFF” it could be dated to the 1897 – 1911 time period. In 1905 Honus Wagner, a star for the Pittsburgh Pirates, signed a contract with Hillerich & Bradsby co. and became the first player ever to endorse a bat. If the bat has a player endorsement it would be dated after 1905. The bat, if a store model could still be worth hundreds. A game used or pro bat could be worth thousands. To help you put a value on your bat I would need more information.
