1974–75 Gary Carter Rookie-Era Game-Used Hillerich & Bradsby Professional Model Bat – MEARS A10 – Possible Finest Known Example (Greenshields Collection) 

Presented here is an exceptional Gary Carter game-used Hillerich & Bradsby professional model bat dating to his rookie season in 1974–75, authenticated and graded MEARS A10 — a coveted perfect grade rarely awarded to professional model bats. Publicly offered Gary Carter rookie-era bats receiving a perfect A10 designation appear to be exceptionally scarce, with few, if any, comparable examples documented at public auction.

Widely regarded as one of the greatest catchers in baseball history, Gary Carter built a Hall of Fame career defined by elite defense, leadership, and offensive production. A key figure for both the Montreal Expos and New York Mets, Carter was an 11-time All-Star and central contributor to the Mets’ 1986 World Series championship team. Early-career game-used bats from Carter’s formative Montreal seasons are especially desirable among advanced collectors.

This bat is a Hillerich & Bradsby K55 signature model manufactured during the 1974–75 labeling period and matches factory specifications and player characteristics consistent with Gary Carter’s documented professional use.

MEARS assigned the bat a coveted A10 grade after confirming extensive game-use characteristics and strong player-specific traits.

Key characteristics noted by MEARS include:
Heavy game use throughout
Heavy ball marks visible on barrel
Correct uniform number “8” on knob end
Medium pine tar handle preparation
Factory records match confirmed
Professional player characteristics consistent with Gary Carter use
