Donald Trump has a unique writing name signature. How much would you pay for his autograph ?

I actually have his autopen autograph...on a photo of himself and the first lady standing in front of Air Force one I received it in 2019 after I donated about $2000.00 to his campaign.

I also have his signature on a bunch of sharpie markers I bought from his merch store. I THINK the signature might ALSO be on the drinking straws I bought from his merch store. Maybe.
