Somebody had to put the card in front of the man
Not by a margin. By multiples that sit outside the rest of the market entirely.
Three cases
Ty Cobb. A 1909-11 T206 tobacco card, posted to him in the 1940s and signed. It made $192,000. His next-highest recorded result is about 8.9 times smaller, and the rest of his market runs from four and a half thousand to twenty-two.
Jim Thorpe. A 1933 Goudey Sport Kings, signed and inscribed with the year 1946. It made $88,800. That is thirteen times his next result, and every other sale recorded here sits between $3,300 and $6,710.
Michael Jordan. Nine 1986-87 Fleer rookie cards, signed at his golf course in Florida in private, with witnesses present. Two of them sold for a combined $5.2 million.
Different decades, different sports, different auction houses. The same object.
What the object actually is
It is worth being precise, because the category is narrower than it sounds.
This is not a signed card in general. The modern hobby produces those in enormous volume: a manufacturer ships blank card stock to a player, he signs a few thousand under supervision, and they go into packs as inserts. Those are plentiful and priced by which card they are.
This is the opposite. It is a card that already existed, printed years or decades earlier, that somebody physically carried or posted to the subject and asked him to sign.
That requires three things to coincide.
Somebody owns the card. Not a reprint, not a modern issue. The original, from the era.
Somebody has the idea. Most people bringing an item to be signed bring a photograph, an index card, a ball or a programme. Bringing a thirty-year-old cigarette card is an unusual instinct.
And the subject is still alive and willing. Which is a window, and for most of these men a short one.
Why the multiple is so large
Because the scarcity is in the combination, not in either half.
Cobb signed enormously and lived until 1961. His signature is not scarce. Thorpe signed programmes on the banquet circuit for years. Jordan has signed under contract for decades.
Nor are the cards themselves the rarest things in the hobby. T206s exist in quantity. The 1986-87 Fleer Jordan is one of the most printed valuable cards there is.
What almost nobody did was bring the two together.
Every other category on this index has a supply that somebody was producing deliberately. Manufacturer signings were scheduled. Show signings were sold by the hour. Joe Louis stood in a casino lobby for eleven years. These objects have no programme behind them at all. They exist because individual people acted on an idea, and the number of people who had it is very small.
What the multiples are not explained by
Three things worth ruling out, because each would be the obvious answer.
It is not the grade. The Cobb T206 carries a card grade of Good 2. The Thorpe Goudey is graded Authentic, meaning no numeric card grade at all. If condition were driving this, neither would be near the top of its market.
It is not the autograph grade. Cobb's is a 7. The rest of his market includes 9s and 10s that sold for a fraction as much.
And it is not simply that cards beat paper. Thorpe's market includes a modern card built around a cut signature, and it made $6,710 against the Goudey's $88,800. Being a card is not the point. Being that card is.
The inscription helps
One detail recurs and is worth noting.
The Thorpe Goudey is inscribed with 1946, the year he signed it. The card was printed in 1933.
That single number does something no certificate can: it fixes the gap. It tells you the card was thirteen years old when the man held it, and it makes the whole transaction legible. Somebody found a card from his playing years, got it in front of him, and he dated it.
We have written about how inscriptions usually reduce value, and about why a dedication is quiet evidence of authenticity. A date on a card of this kind is a third case again: it is not a dedication to a stranger and not a statement of achievement. It is documentation.
What to do with this
Three things.
Read the card's date against the signature's date. On a signed vintage card the gap between the two is most of the story, and it is rarely stated in a listing. A 1933 card signed in 1946 and a 1933 card signed in 1933 are different objects with different explanations.
Do not price it off the signer's normal range. Everything else this index records for these men would lead you to a number an order of magnitude too low. The category has its own market and very few comparables.
And treat provenance as the whole ballgame. These are the objects a forger has the most reason to manufacture, because the premium is enormous and the population is tiny. A documented chain back to the person who asked is worth more than any opinion about letterforms.
The thing worth sitting with
In the 1940s somebody in America put a handful of cigarette cards in an envelope and posted them to Georgia, because it occurred to them that the man on the cards might sign them.
Somebody else got a 1933 gum card in front of Jim Thorpe, who wrote his name across it and added the year.
And in our own time somebody carried nine copies of a rookie card to a golf course in Florida.
None of them was doing anything clever. They were doing the obvious thing, which almost nobody else did, and it turned out to be the most valuable idea in the hobby.
This index records Cobb, Thorpe and Jordan with both grades shown separately. You can read how we work the numbers out.
