Fashioned from plated brass and inscribed inside with the date “June 15th 1863,” the man’s ring shown here is less ordinary than it looks. It hides a small box intended to be filled with a toxin. A hinged lid on the box is slotted to allow a small, sharp blade to snap out when the wearer pushed a button on the ring’s side. With the poisoned blade exposed, the attacker could clandestinely poke his victim and (one presumes) make a hasty getaway. The owner of the ring—and whether it was used as intended during the Civil War—remains unknown.
