Marking the end of the flagship line for the '18 season, 2018 Topps Update Series Baseball goes big on the MLB rookies and trades to fill out the roster. Joining Series 1 and Series 2, 2018 Topps Update Series Baseball brings 300 more base cards to the flagship mix. The familiar parallel lineup is also in play. Continuing a few insert lines while sprinkling in some new choices, the checklist is anything but small! Box formats include Hobby, with one autograph or relic, and Hobby Jumbo, which contains one autograph and two relics per box. An added incentive for collectors, Update is part of the Silver Pack 1983 Chrome promo that rewards box purchases with free packs. Each Hobby box is good for one pack, while Jumbo earns two. 10 cards per pack, 36 packs per box. 50 cards per jumbo pack, 10 packs per box.
