What does a Joe Louis autograph cost?
The results recorded here run from around seventeen hundred dollars to twenty-two thousand, and every one is a signed card from the late 1940s or early 1950s. Three of the four came from a single consignment on the same day, which is worth knowing when reading the spread: they are one seller's collection rather than four independent tests of the market.
Why did the only known signed example sell for a third of a common card?
This is the clearest thing on the page. A 1951 Topps Ringside, described by the auction house as the only signed PSA example in existence, made six thousand seven hundred and ten dollars. A signed 1948 Leaf, a card with no such claim attached, made twenty-two thousand two hundred. A population of one sold for less than a third of something ordinary. Uniqueness is a genuine fact and it settles very little on its own: the Leaf is the more collected card, from the more collected set, and that turns out to matter more than being the only one.
Why is his market cards when Muhammad Ali's is photographs and magazines?
Because of when they fought rather than what they fought. Louis held the heavyweight title from 1937 to 1949, which is exactly when American card companies were producing boxing sets: Leaf in 1948, Topps Ringside in 1951, the Exhibit Supply Company's arcade cards through the same years. There were cards for him to sign. By Ali's era the boxing card had largely disappeared and the magazine cover had taken its place, which is why his market on this index leads with photographs and magazines, and Sugar Ray Leonard's leads with magazines outright. The object a signer's market is built from is mostly a fact about what existed to be signed.
Signatures are reproduced more often than most buyers realise, by outright forgery and also by machines and assistants signing on somebody’s behalf. Every item on this page has been examined by PSA/DNA, JSA, Beckett, SGC or CGC, and this index carries nothing else. That is a deliberate restriction, and the investigation that created the modern authentication industry is worth reading, along with what a certificate actually claims.
