Continuity mistake: In a scene set in 1862, Harold Lloyd portrays his own grandfather, a Confederate soldier. An elderly woman gives him a tiki-like lucky charm which she says will protect him as he confronts leaders of the Union Army. After he successfully fights off two soldiers he holds the charm in his left hand, but the close-up shows the charm in his right hand, then it's back in his left hand in the next shot.
