Navy passport holder with RFID and boarding-pass pocket

I lost my navy blue passport holder with RFID blocking yesterday around 3pm outside Grand Central Terminal on 42nd Street. It's a compact Travelon-brand holder, navy nylon with a red stitch detail and a small external zip pocket. Inside I kept my passport and my boarding pass, plus a tiny green SIM card sleeve. There's a coffee stain on the back and the front has faint gold initials 'EP' embossed. It has sentimental value—it was a gift from my sister before a big trip, and I really need it back for my upcoming flight to Lisbon. If anyone found it, I’d really appreciate getting it back; I can meet near Bryant Park or arrange pickup.
