2026 Leaf Metal Baseball Checklist and Details
2026 Leaf Metal Baseball brings back one of Leaf’s most autograph-focused baseball releases with a checklist that mixes legends, current draft names, and some of the sport’s most closely watched prospects. The product leans heavily into ink, but it also includes a base set, multiple insert lines, and several multi-signature concepts that give collectors plenty of directions to chase.
This year’s edition also adds new ideas to the familiar Leaf Metal formula. The checklist includes players from the 2025 MLB Draft, along with a broad mix of prospects and retired stars, while the product structure expands with two box formats that are both larger than last year’s versions.

What Collectors Can Expect in the Checklist
While autographs are the main attraction, 2026 Leaf Metal Baseball does begin with a base set and several insert themes. The checklist is built around a wide range of names, from top prospects to retired players, and the product uses a mix of base, autograph, and insert formats to spread those names across the release.
Among the featured concepts are die-cut Hit Kings, vintage-inspired 1950 Leaf, and Stainless cards. Additional insert sets include Draft Dreams ’25 and 1991 Gold Leaf Prospects, both of which build on earlier Leaf themes.
Another notable insert family is Armed And Dangerous, a pitcher-focused checklist that comes in three background variations: Space, War, and Western. These cards are available in both base and autographed versions. Explode Onto The Scene rounds out the insert lineup with a spotlight on rising talents.
Autograph-Only Sets
Several autograph-only sets are also part of the product. Those include die-cut Skywriting, Metal X, and Lunararity. Collectors looking for multi-signature cards will also find Metal Duos, hard-signed Leaf Metal, and TRItanium.
