Due to the nature of the set, Topps Now doesn't have a set checklist. These are traditionally sized cards, not over-sized prints like a lot of Topps other online exclusives.
All Topps Now cards have a limited 24 hour print run. Only what is bought within 24 hours ends up being the total print run of the card.
Some cards are quite rare with some having just 27 copies. Topps NOW is a product line from Topps that stared in 2016 and depicts the greatest moments and milestones from the Major League Baseball season, WWE, MLS, Premier League, UFC, CULTURE, SPACE LANDINGS, ROYAL CORONATION and even the Preacher TV Series.
