When Scout noticed something "winking at me" on a sunny afternoon as she "raced by" the Radley oak, she screwed up her courage and decided to investigate. Some shiny tinfoil caught her eye, and when she retrieved it, the object turned out to be "two pieces of chewing gum minus their outer wrappers." Boo must have removed the paper wrappers to deliberately expose the tinfoil in the hope that one of the children would see it reflect in the sunlight. As Jem and Scout walked home on the last day of school before summer vacation, Scout spotted another piece of tinfoil in the same spot as before. This time Jem grabbed it, and when they inspected the object after they got home, the children found that the foil had been shaped into a miniature box: Inside were "two scrubbed and polished pennies... Indian-heads."
