Paul was spotted leaving the coins on train tracks to flatten them so he can use them to play his guitar
Paul left coins on the rails near his home so trains would flatten them.
He returned later to collect them.An onlooker said: “Normally it’s kids who leave coins on the track, not a grandad. It was only when he returned did the penny drop – perfect plectrums.”
Macca, 77, wearing shorts, T-shirt and a Team GB Olympic cap, placed a dozen one-cent coins on the Long Island Rail Road in New York’s Hamptons. Paul was once said to have worn acrylic nails to stop his fingers bleeding, but returned to a plectrum.
Other musicians, including Queen’s Brian May, have used flattened coins as plectrums because the metal is strong.
