Blue RFID passport holder with boarding passes

I lost my blue RFID passport holder yesterday around 3pm near Pike Place Market, outside the main entrance on Pike Street by the Gum Wall. It’s a compact blue faux-leather wallet, RFID-blocking, about the size of a passport, and it has a small coffee stain on the bottom corner plus silver initials 'AK' embossed inside. Inside are my passport, a boarding pass, and a couple of cards; it feels a lot less secure without it, and it’s sentimental—my grandmother gave it to me. If anyone found it, I’d really appreciate getting it back.
