2021 Donruss, 2021 Topps Series 1, and 2021 Topps Inception are making their debut in this month’s Price Guide. 2021 Topps Opening Day is partially priced below. 2021 Topps Heritage and 2021 Topps Definitive went live shortly before our pricing deadline, not allowing sufficient time to establish secondary market values. 2021 Topps Tribute and 2021 Panini Select were scheduled to go live in the weeks following our deadline. Be sure to check out the Online Price Guide on Beckett.com throughout April and May for pricing on these products - weeks before it will appear in the next issue of Beckett Baseball.
