In To Kill a Mockingbird, what is the first gift that appears in the hollow of the tree? What else do they find?

The first gifts Jem and Scout receive from Boo Radley in the knot-hole of the tree are two sticks of Wrigley’s Double-Mint gum. Scout, who finds them, is at first suspicious, especially as the gum is unwrapped from its foil, but once she takes the gum home and sniffs it, she decides it is okay and stuffs it in her mouth.
The next gift is a purple velvet box with two Indian head pennies inside. The box is "patchworked" with folded bits of tinfoil from chewing gum wrappers. The pennies have been polished.
Other gifts include two soap carved figures that represent Scout and Jem, conveying that the gifts are meant for them, and a broken pocket watch on a chain with a knife attached.
