Warren Motts, who runs the Motts Military Museum in Groveport, called firefighters after the 90-year-old woman dropped off the shell.
The woman said her deceased husband had been given the shell as appreciation for his service during World War II and she thought the museum might like it.
Authorities confirmed there was no danger. Motts says the museum will definitely keep the shell.
