2025 Topps Series 1 Baseball kicks off the new season in a way that emphasizes both tradition and moving forward. The checklist keeps with the past couple of decades, going big with an assortment of inserts that go far beyond the central base set. Other foundational elements remain as well but they’re joined by some chase elements as well. Collectors will find several different configurations including both hobby and jumbo. The main base set clocks in at 350 cards. Veterans and rookies are the main focus. They’re joined by such subsets as Future Stars, League Leaders and team cards. It is worth noting that this is the first of two planned releases for 2025 Topps Baseball. Both are intended to go together to form one larger base set. This means some big stars are missing from Series 1. That’s likely because they’re already planned for Series 2. Foil is the theme for many of the parallels, offering more colorful takes on the base set. All told, every card in the set has more than 50 different versions. This includes several exclusives including a new batch of spring-themed Holiday cards found only in tins. Despite the large number of parallels, some long-running themes like Black, Father’s Day Blue and Mother’s Day Pink are not on the 2025 Topps Series 1 Baseball checklist. First Card versions come with a special stamp. These are intended to indicate the first copies of each card that were produced.
