Blue US passport with embossed seal

I lost my navy-blue US passport yesterday around 3:45pm in downtown Wausau, near the Wausau Center Mall on Grand Avenue. It's the standard passport book, about 4.5 by 3.5 inches, with the embossed US seal on the cover. The back cover has a small coffee stain and a faint crease along the lower edge from a spill and a quick drop on the sidewalk. Inside there's a visa page with a Jamaica stamp that’s partially visible. This passport is essential for my upcoming trip and holds a lot of sentimental value; I’d be grateful to get it back.
