There are things that go unsaid, things we are only allowed to think but are all aware of.
The older an actor gets, the higher their signature's value climbs.
The less an actor signs, the higher the price of their autographs.
That's how it is; it's the law of supply and demand, coupled with speculation on the artist.
Johnny Depp, Leonardo DiCaprio, Robert Redford, Nicole Kidman, Bruce Willis, and many others do not sign many photos, posters, or items. The price of their signature will therefore be high because their autograph is rare.
Legendary icons who are getting older have also seen the price of their signatures rise very quickly since 2020. Their age, approaching or having passed 80, makes wallets tremble. Among these actors, we can note Arnold Schwarzenegger, Sylvester Stallone, Anthony Hopkins, Robert De Niro, Al Pacino, and even Clint Eastwood.
In 2020, I had Eastwood pieces for $400; now it's $1200 minimum.
Bruce Willis, the youngest of the bunch, really only signs very rarely, but being afflicted by illness, the price of his signature will surely soar before long. It's tough to read, but this is a fact of speculation.
Michael J. Fox, Matt Damon, and John Travolta sign a lot; their signature therefore has less value because their footprint is less rare on the autograph market.
The case of Matt Damon is even more amusing as the actor has said he never wants to refuse to sign because his wish is for his signature to have no resale value; he wants to get close to absolute zero in market value. So he signs everything presented to him. Bad luck, his autographs still sell very well!
As for Michael J. Fox, he also signs a lot. At first, I thought this was normal due to the fact that his illness had forced him to stop his career and that signing sessions were now his only income (he charges $250 for a signature, nonetheless). Well, no, it actually turns out that the actor donates a huge amount to his foundation for fighting Parkinson's disease! And this same foundation, in 2023, donated $600,000 to a French biotechnology laboratory. Honorable.
Schwarzenegger has a skyrocketing value. As an example, an online auction that took place on August 30, 2025, for a T800 bust signed in an edition of 200 by Mr. Muscle. I have been able to acquire 6 of these items over the last six years. Their price has always fluctuated between $600 and $1100. See on the right in the image the price at which it sold on August 30th. Granted, it was the last piece out of the 200, but that was an industrial accident!
The price of the only piece I have left (as of the writing of this article) has consequently had to be adjusted to this law of supply and demand! But who knows what it will be worth once the actor is no longer with us... (morbid, right?)
In effect, this type of sale has the impact of raising all prices concerning the actor. It is the same principle as in an auction house: when a painting, a sculpture, or other item usually sells for, say, €100, if one day the same object reaches a higher or even much, much higher value like €1000, its new value is therefore the latest one. Note that this is less applicable in reverse, because if an object that usually sells for €100 sells once for €50, its value will lose very little (10 or 15€) or nothing at all, but it will slow down its upward progress.
