2021 Topps Japan Edition Baseball Checklist

A 220-card MLB set with Japan-focused inserts, relics and autographs

2021 Topps Baseball Japan Edition is a Japan-market MLB set, filed in Topps's checklist archive as 2021 MLB Japan Edition. A 220-card Base set covers established stars and rookies, and two insert themes tell the story of baseball's links with Japan: Japanese players who came to MLB, and MLB teams and stars who have played in Japan. Both themes also appear as relic cards, alongside a 30-card autograph checklist.

What's in the checklist

• Base: 220 cards, #1 Fernando Tatis Jr. through #220 Mike Trout. Cards the checklist flags as Rookie are marked RC
• Parallels: no parallels or serial numbering are listed
• Inserts: Japan Comes to MLB (JCM-1 to JCM-10) and MLB in Japan (MIJ-1 to MIJ-15), plus matching relic cards: Japan Comes to MLB Relics (10 cards) and MLB in Japan Relics (15 cards)
• Autographs: Topps Japan Edition Autographs, 30 cards with TJA codes, mixing Rookie-flagged players with veterans and legends such as Hideki Matsui, Ichiro and Greg Maddux

Key subjects

Shohei Ohtani (#74, JCM-3, relic JCMR-SO and autograph TJA-SO), Mike Trout (#220 and autograph TJA-MT), Jazz Chisholm (#152, Rookie) and Ryan Mountcastle (#143 and autograph TJA-RM, both flagged Rookie).

Grading considerations

Check centering, corners, edges and surface on every card, looking for print lines and dents. On relic cards, look at the window edges and the memorabilia for lifting, tears or debris. On autographs, check the signature for smudging, skips or fading, and check where it sits on the card. Match the card code to the checklist. A checklist establishes identity, not condition.
