Lost & found passports in St Augustine

Blue U.S. passport, lost near Castillo de San Marcos

I lost my blue U.S. passport yesterday around 3:15pm near the Castillo de San Marcos. It's a standard-size passport book, slightly worn at the corners, with a faint coffee stain along the bottom edge and a gold seal on the cover. Inside the back cover there's a small charity-run sticker from a local event I did last summer, and my name is lightly printed on the inner page. I would really appreciate getting it back so I can travel without delay.
