Lost brown leather passport wallet containing passport, cash, and travel cards in Nottingham city center near bus stops.

I misplaced my brown leather passport wallet while rushing to catch a bus in Nottingham city center. It has my passport, some cash, and a couple of travel cards. I last remember putting it in my backpack before I got on the bus, but I must have dropped it while disembarking or in a hurry. It means a lot to me, and I'm hoping someone finds it.
