SHU staff ID badge on blue lanyard

I lost my Sheffield Hallam University staff ID badge yesterday around 3pm. It's on a blue fabric lanyard with a small silver clip. The badge itself is a white card with my photo on the left, the SHU logo at the top, and my staff number SHU-2049 on the bottom. There's a tiny coffee stain along the lower edge of the plastic sleeve and a slight dent on the bottom left corner. I last had it outside the Peace Gardens near Sheffield City Hall, while I was heading toward Fargate for a quick meeting. Without it I can't access my department's doors, which is pretty stressful since shifts start soon. If someone found it, I'd really appreciate getting it back; I'm reachable at [email protected].
