Black leather contact card holder with initials AF

I lost my black leather contact card holder yesterday around 3pm near City Hall, outside the Broad Street entrance on Market Street in Philadelphia. It's a slim card holder, about the length of a credit card, with a smooth matte finish and a tiny suede pocket inside. On the front, there's a small gold-embossed 'AF' initials, and the back has a faint coffee stain from a morning cup. Inside are two contact cards with my name, Amina Farouk, and my work email. It has real sentimental value because it belonged to my mentor, and I really need it back so my clients can reach me.
