2018 Topps Now Offseason Baseball allows collectors the opportunity to build their print-to-order MLB set during the winter months with more online-exclusive options.
Although the primary 2018 Topps Now Baseball set covers the regular season and postseason events, the 2018 Topps Now Offseason Baseball checklist picks up after the final out of the 2018 World Series win for the Boston Red Sox. They are easy to identify as the card numbers have an #OS prefix.
Generally, 2018 Topps Now Offseason Baseball releases cards much less often than the main set, but there are still multiple cards of note. This includes the World Series parade in Boston, various MLB awards finalists and winners, any winter trades or free agent signings, and just about anything else Topps can put on a card.
While most of the cards stick to the 24-hour sales period, the Award Finalist cards are available for several days leading up to the official announcement of the winner. Collectors who purchase the winning player earn a free bonus card.
There is also a special #RC set with on-card autographs for the 2018 Topps MLB All-Star Rookie Team. If you buy the entire 12-card base set, you earn a free bonus card.
