2026 Topps Museum Collection: parallels worth chasing

2026 Topps Museum Collection Baseball is scheduled to come out on November 11. We have Topps' full checklist and odds sheet loaded for it: 145 parallels across the base set, the autographs and the relics. Here is how the chase is laid out, from the easiest numbered cards down to the 1/1s.

One box type, so no exclusives

Every parallel on Topps' odds sheet for this set is listed under hobby boxes. There are no jumbo or retail versions to track down, so nothing here is locked to one kind of box. If you want to know why that matters in other sets, see Hobby vs Jumbo vs Breaker's Delight vs Retail.

The base parallel ladder

The base cards come in these numbered colors, with Topps' listed odds:

• Gold /275 (1:2)
• Pink Sapphire /199 (1:3)
• Sapphire /150 (1:4)
• Amethyst /99 (1:5)
• Ruby /75 (1:7)
• Amber /60 (1:8)
• Blue Topaz /25 (1:19)
• Black Diamond /10 (1:46)
• Diamond /5 (1:91)
• Printing Plates 1/1 (1:114)
• Emerald 1/1 (1:456)

There is also a Turquoise base parallel (1:10). We don't have a print run for it yet, so check the card itself before you treat it as numbered.

A color doesn't mean the same number everywhere

This is the part that trips people up. In Museum Collection, the gem names carry over from the base set to the autographs and relics, but the print runs don't. A few examples from the checklist:

• Ruby is /75 on base cards, /20 on Archival Autographs, /15 on Meaningful Material Relics and /5 on Showpieces.
• Sapphire is /150 on base cards, /50 on Archival Autographs and /25 on Showpieces.
• Gold is /275 on base cards, /149 on Archival Autographs and /10 on Showpieces.

So a "Ruby" listing tells you very little on its own. Check the stamped number and which insert it is. Our print runs guide covers how to read the stamp.

Where the 1/1s are

Emerald is the 1/1 color. It is a 1/1 on the base set and on 16 of the autograph and relic sets, including Archival Autographs, Showpieces, Pastime Portraits, Atelier Autographed Book Cards, Lifetime Members Relic Autographs and Written In History Relic Autographs. The base Emerald (1:456) is the easiest of them on paper. The Dual On Card Autographs and Pastime Portraits Emeralds are the hardest, both listed at 1:5,553.

The relic 1/1s are named after the swatch. Museum Memorabilia has three: Laundry Tag (1:245), Sleeve Patch (1:255) and MLB Silhouetted Batter (1:256). Below them sit Team Logo /5 and Jersey Number /10.

The framed cards use frame colors. Museum Framed Autograph Relics run Silver Frame /25, Gold Frame /10, Black Frame /5 and Wood Frame 1/1 (1:1,216), with an unnumbered Bronze Frame at the bottom.

Printing plates on the base set are 1/1s too, at 1:114. If you're not sure whether a plate counts as a true one of one, our 1/1 guide explains it.

The longest odds in the set

The Wood Frame version of the Framed Hall Of Fame Autographs is listed at 1:22,210, the longest odds on the whole sheet. We don't have a print run for it yet.

Before you buy one

Since the same color name shows up at so many different numbers, it is easy to overpay for the wrong one. Match the name, the insert and the stamped number against the checklist. Our guide on checking a numbered parallel walks through the rest.
