Lost dark brown leather wallet with coffee stain inside and important cards, lost in Kearsley Park, Flint.

I lost my dark brown leather wallet while walking my dog in Kearsley Park, Flint, yesterday afternoon. It contains my driver's license, several credit cards, and some cash. There’s a small coffee stain on the inside, and my contact information is written on a card inside. I would greatly appreciate any help in finding it!
