These bats all bear the player’s endorsement on the upper barrel, represented with a facsimile signature. In addition to the autograph, the burned-in stamps include the service marking (above the endorsement) and an additional mark beneath. The absence of a listed knob marking indicates that we were unable to obtain that detail or that particular bat lacked such a mark.

This list of bats constitutes those that we have observed in collections, marketplace or exist within the Chevrons and Diamonds Collection. All of these models are stamped with “125,” some with the endorsement player’s initials. On the upper barrel, stamps include “Louisville Slugger” and can also include “GENUINE.” Most of these models include “Powerized” adjacent to the center brand while some variants may be stamped with “Oil Tempered.”
