Choosing between sports memorabilia cards can mean deciding whether you want a player-centered showpiece or a focused addition to a particular set, team, or rookie collection. Here, the Lionel Messi Museum of Materials card and Ivan Rabb Art Nouveau card both carry memorabilia features, but they serve very different collecting directions: MLS and Messi on one side, NBA Court Kings and a rookie insert on the other.
Quick verdict
Choose the 2026 LEAF ART OF SPORT MUSEUM OF MATERIALS LIONEL MESSI GAME USED MEM MLS LOGO/4 if Lionel Messi and Major League Soccer are the central theme of your collection. It is a 2026 Leaf card with a /4 print run and game-used memorabilia in its description.
Choose the 2017-18 Panini Court Kings - Art Nouveau Ivan Rabb #AN-IR (MEM, RC if you are building around 2017-18 NBA cards, Ivan Rabb, or Panini Court Kings. At USD 2.99 versus USD 1,399.00 for the Messi card, the two choices occupy a notably broad listed-price range.

Where each card wins
The Messi card wins for scarcity-minded MLS collecting. Its /4 print run gives the card a tightly defined numbered format, while the title and description place Lionel Messi and an MLS logo memorabilia element at the center. That makes it the natural pick when one soccer player is the priority rather than a broader NBA set build.
The Rabb card wins for Court Kings rookie-insert collecting. It is identified as card #AN-IR from the Art Nouveau insert set, with Rookie, Insert, and Memorabilia features. Collectors pursuing a 2017-18 Panini Court Kings run or an Ivan Rabb/Memphis Grizzlies-focused card grouping have a clear fit here.
Product notes
2026 LEAF ART OF SPORT MUSEUM OF MATERIALS LIONEL MESSI GAME USED MEM MLS LOGO/4
This is the choice for a collection that puts Lionel Messi and MLS memorabilia ahead of set completion. The card is a Leaf Museum of Materials entry with a stated /4 print run, and its description calls out game-used memorabilia featuring an MLS logo piece. It also has standard card size and 130 Pt. thickness, useful details for collectors organizing cards in uniform holders or display formats. The key limitation is that it is ungraded and explicitly not autographed, so the appeal rests on the Messi subject, memorabilia format, and numbered run rather than an autograph or assigned grade.
2017-18 Panini Court Kings - Art Nouveau Ivan Rabb #AN-IR (MEM, RC
The Ivan Rabb card makes the most sense when the target is the 2017-18 NBA season, Panini Court Kings, or a rookie-era Rabb card. Its Art Nouveau designation gives it a specific insert-set identity, and the listed Rookie, Insert, and Memorabilia features make it more targeted than a standard player card. The description connects Rabb with the Memphis Grizzlies and identifies a game-worn material piece, adding another collecting angle for team-oriented binders. Its limitation is also an ungraded condition; the listed parallel/variety is [Base], so the card's draw is its named insert and rookie memorabilia combination.
Final choice by use case
Pick the Lionel Messi Museum of Materials card for a Messi-centered soccer display, an MLS memorabilia focus, or a numbered-card collection. Pick the Ivan Rabb Art Nouveau card for a Court Kings project, an NBA rookie-card grouping, or a Memphis Grizzlies-oriented collection. Both are ungraded memorabilia cards, so the deciding factor is primarily the player, league, and style of collection you want to build.
