Returning for a second MLB season, 2021 Topps Allen & Ginter Chrome Baseball again applies a chromium finish to A&G. Just like last year's debut edition, collectors can find multiple Refractors/inserts per Hobby box and also chase the case-hit autographs.

Taking the main Allen & Ginter design and adding Chrome, 2021 Topps Allen & Ginter Chrome Baseball features 300 cards in the base set. This includes baseball stars along with various champions from other sports and pop culture figures. Working with a slightly larger rainbow compared to 2020, each box includes six base Refractors and 18 Mini cards (one per pack).

New base options include X-Fractor (one per case) and Blue Refractor (#/150). For the minis, there are new Gold Refractor (#/50) and Orange Refractor (#/25) cards.
