Red lobster-shaped keychain with initials J.S.

Found this afternoon a small red enamel keychain shaped like a lobster, about 2 inches long. It's on a frayed black lanyard and has a tiny silver dot on the tail. The lobster has 'J.S.' engraved on the back, plus a faint scratch along the shell. I found it around 2:15 pm today near the Daytona Beach Boardwalk and Pier, along Ocean Avenue by the lifeguard station. It feels like it could be sentimental or a gift, so I’d love to return it to its owner if you recognize it.
