The "Star Wars" star helps fans determine if his autograph is real or fake.

— -- Mark Hamill fans have another reason to love him.

The "Star Wars" actor has taken to Twitter to verify his autograph on memorabilia in order to "beat the dealers."

It all started Saturday when a fan asked him if his signature on a comic book was real or fake.

With so many forgeries out there, I'm happy to tell you that this one is REAL. Enjoy! https://t.co/UhayldDJlw

Soon, other fans were asking him to confirm whether his signature on various items was a forgery or the real deal.

In a word- NO. I'm so sorry there's so many fans spending their hard-earned money for fraudulent signatures. #FAKE https://t.co/717Bv02ASA
