Burgundy UK passport with gold crest, lost near Paradise Street

I lost my burgundy UK passport yesterday around 3pm after grabbing coffee by the Paradise Street entrance to Liverpool One. I think I dropped it somewhere between Bold Street and Lime Street Station, maybe near the Primark on Church Street. It's in decent condition, but the back cover has a small coffee stain and the top-right corner is bent from living in my pocket all week. There's a tiny photo tucked in the inside pocket of the passport cover—my sister when she was a baby—and that little detail has always made it extra personal. This passport is essential for work trips and travel, I really need it back.
