Ohtani autographs, by how they were signed

Five separate autograph markets, why third-party authentication is not certification, and what the catalog can verify about each.

A third-party-authenticated in-person signature is a genuine signature on a different asset — it never prices a pack-issued certified autograph, and this app refuses to let it.

For a player at this level the in-person signing market is far larger than the pack-issued one, and the two produce objects that look similar in a listing photo and trade at completely different prices. Everything on this page is organised around keeping them apart.

The distinction is not about authenticity. A reputable third-party authenticator establishing that a signature is genuine is a real and useful thing; it simply answers a different question from the one a certified autograph answers, which is that the manufacturer signed the card and inserted it. So an authenticated in-person signature is shown here as its own family, and its sales are structurally prevented from entering a factory autograph's comp pool — the identity key carries the signature class, and the comp filter refuses the mismatch rather than discounting it.

Redemptions, buybacks and cut signatures are separated for the same reason. A redemption is a voucher, not a card; a buyback is an original card re-issued; a cut signature is a signature mounted into a card that was manufactured around it. Each is pack-issued, none is the same asset as an on-card autograph of the same year.

What the rows below rest on

9 identities in scope: 0 source-verified, 9 provisional, and 0 assembled from marketplace listings with no catalog source at all.

Corroborated only at search-snippet level; the source page itself has not been opened and re-read. Treat every detail here as a claim awaiting confirmation, not as an established fact.

None of them has a live listing or a confirmed sale on record yet, so there is no price on this page to read.

Signature status unknown

The catalog has not established whether this identity is signed. Unknown is not 'no'.

What this market punishes

  • • Authentication answers 'is this signature real'. Certification answers 'did the manufacturer sign and insert this card'. A slab can carry the first and say nothing about the second.
  • • A redemption may never be fulfilled, and an expired one is a slip of paper. Its price is its own market's price.
  • • Where the catalog cannot establish how a card was signed, it says unknown. Unknown is not 'factory'.
  • • Print run ≠ graded population. The serial on the card is fixed at manufacture; the graded population grows every time another copy is submitted. Never read one as the other.
