In reality, most unexpected items found on cars have everyday explanations. Parking lots are busy, unpredictable environments—people drop loose change, kids run around, and objects get brushed or bumped into unusual places. Often, a coin in a door handle is simply the result of an accident, a child’s curiosity, or a piece of stray clutter that ended up somewhere surprising. It’s easy to overthink unusual details, but in the vast majority of cases, they’re harmless coincidences rather than signs of mischief.
