The 2024 Topps Heritage High Number Baseball set continues the tradition of bringing vintage-style designs to modern-day stars, rookies, and traded players. Modeled after the iconic 1975 Topps Baseball design, this release builds on 2024 Topps Heritage Baseball by adding key rookies, late-season call-ups, and players who switched teams during the season. Staying true to Topps’ historical roots, High Number pays homage to the early years of Flagship Baseball when cards were issued in multiple series, with the later releases often featuring fresh faces and roster updates.
