It looks like despite her hefty "Amazing Spider-Man 2" paychecks, Emma Stone prefers to tote around quarters.

According to Us Weekly, during a chat with the "Late Show" on Wednesday, July 16th, Andrew Garfield's 25-year-old girlfriend revealed that other than her money as an actress she has an additional source of income.

Emma Stone told David Letterman about how her late grandfather has had a big influence on her coin collection.

She explained, "There's a long family history with quarters," adding, "My grandfather leaves quarters. It's just amazing."

Stone insisted, "It's him!"

The "Easy A" starlet went on to tell the host, "It's absolutely him."

Letterman, 67, clarified Emma Stone's story asking the starlet, "This is your late grandfather, and you find a quarter, 'Oh, I bet that's from granddad?'"

The redhead answered, "Yes," adding, "Who I never met! It's exactly like that. It's that. It's such a long story that you'd have to go to commercial five times and roll to a clip and then come back and I'd still be telling the story. But it's him! You guys, it's him."

When the host told the actress that he finds it difficult to believe that supernatural encounters are real without any scientific proof, Stone insisted that it is possible.

The actress who played Gwen Stacy said, "That's the joy of it!"

She continued, "It's not a logical thing -- it's magical."
