Which Konnor Griffin rookie are you trying to buy?
The official PDF organizes its base checklist into several groups, including Rookies and Rookie Debut. A player search can find both. Decide which record you want before comparing sold listings, because a listing that says only Griffin Update RC leaves the specific card unresolved.
For a two-card Griffin base project, put US1 and US255 in different rows. Add the card’s actual image, finish and condition to each. Two copies of one number do not complete the two-card project, and an insert featuring the same player does not substitute for either base entry.
Understand rookie cards versus rookie-year inserts
| Player | Rookies entry | Rookie Debut entry |
|---|---|---|
| Konnor Griffin | US1 | US255 |
| Justin Crawford | US2 | US23 |
| Carson Benge | US3 | US250 |
| Kevin McGonigle | US7 | US140 |
US1 alone does not identify the version
Griffin US1 also appears in the PDF’s Golden Mirror, Player Number, Clear, True Photo and Rookie 1952 variation sections. That is why a number lookup should narrow a search rather than end it. These are checklist identities, not a statement that every version has identical scarcity.
A useful buying description names the product year, full product, player, US number, exact variation and any serial stamp. Then compare front and back photographs with a reliable visual reference. When the evidence is incomplete, keep the variation field unconfirmed rather than copying the seller’s SP label.
The 1952 variation uses a historical design within a modern product. Its design year and issue year answer different questions. A record filed under 1952 because of its appearance will mix a current rookie card with vintage material and produce irrelevant price comparisons.

Schematic. Compare sales only after the identity is complete.
Hobby or Jumbo: reconcile the pack-count discrepancy
The U.S. product page checked October 20 lists Hobby as 20 packs of 12 cards and Jumbo as 10 packs of 40. The Topps Ripped box guide instead says 21 Hobby packs and 12 Jumbo packs. We have not assumed that bonus packs explain the difference: the sources do not reconcile it.
Use the exact listing and sealed-box configuration for the purchase you are considering. Keep any bonus packs in a separate field rather than folding them into the regular pack count. That makes an offer with extras comparable with one without them.
Using the current product-page figures gives 240 regular-pack cards for Hobby and 400 for Jumbo. Those totals are arithmetic, not counts of unique base cards. Inserts and duplicates mean neither number establishes set completion. The same page describes one autograph or relic for Hobby, versus one autograph and one relic for Jumbo.
Interpret autograph-or-relic wording
| Format | Listed regular packs | Listed hit content |
|---|---|---|
| Hobby | 20 × 12 = 240 cards | One autograph or relic |
| Jumbo | 10 × 40 = 400 cards | One autograph and one relic |
Avoid three common set-building mix-ups
Topps describes Update as the 350-card conclusion to its 2026 Flagship run. Set your project scope before buying a lot: ordinary numbered base, one player’s variations, and a full insert collection require different checklists.
Holiday-themed parallels inside Update do not turn those cards into the separate Topps Holiday Baseball product. Likewise, a Chrome insert within a paper product does not establish that the card came from Chrome Update. Read the exact product and section instead of sorting solely by a seasonal design or shiny surface.
Keep the date of the PDF you used. The linked Update file is labeled 10-19; a saved spreadsheet from an earlier source should be reconciled against that revision without erasing notes about the cards already acquired. If two sections disagree, photograph the physical card and flag the disputed row rather than inventing a correction.
Frequently asked questions
What is Konnor Griffin’s 2026 Topps Update rookie number?
The official October 19 revision lists US1 in Rookies and US255 in Rookie Debut. Specify which one, and then identify its version.
Is a Rookie Debut card the same as the ordinary rookie?
It is a separate checklist entry in this product. Keep its number and image distinct when building a set or comparing sales.
Does Griffin US1 identify a Golden Mirror card?
No. US1 appears in several sections, including ordinary Rookies and Golden Mirror. Confirm the actual treatment with front and back photographs.
How many cards are in a 2026 Update Hobby box?
The current U.S. product page lists 20 packs of 12, or 240 regular-pack cards. Ripped says 21 packs, an unresolved difference. Check the exact packaging and record bonus packs separately.
Is the 1952 rookie variation an original 1952 card?
No. It is a 2026 issue using the historical design. Keep 2026 as the issue year in your records.
Does a Jumbo box complete the 350-card base set?
Its nominal card total cannot establish that. Duplicates, inserts and other content reduce the number of distinct ordinary base entries received.
