Lost brown leather travel wallet containing ID, credit cards, and cash at Tri-Cities Airport.

I lost my brown leather travel wallet on October 5th while at the Tri-Cities Airport. It has my ID, several credit cards, and some cash inside. I realized it was missing once I got to my gate. I've checked with lost and found at the airport, but no luck so far. I'm really hoping somebody finds it and returns it to me since it has all my important stuff.
