Blue US passport with gold seal

I lost my blue US passport yesterday around 3pm. It slipped out of my tote while I was grabbing a coffee outside the Humboldt County Courthouse on 5th Street in Eureka, near Old Town. The cover is navy blue with the gold seal; inside you will see my photo page and some Canadian visa stamps, just to know it is mine. There's a coffee ring on the bottom corner of the cover and a tiny crease along the back. This passport is essential for upcoming travel, and I would be grateful to get it back.
