Black RFID passport wallet with red interior

I lost my black RFID-blocking passport wallet by Travelon yesterday around 3pm. It's a compact nylon wallet, about the size of a passport, with a red satin interior and a slightly worn outer corner. I had it outside Reading Terminal Market on Market Street near 12th Street in Philadelphia. Inside I carry my passport photo page, a driver's license, and two credit cards. It also has a small coffee stain on the bottom left corner and my initials 'AP' embroidered on the inner pocket. It really means a lot to me because it was a gift from my grandmother, and I’d be incredibly grateful to get it back if anyone finds it.
