Lost small black zippered pouch containing a collection of vintage and rare coins from the 1800s near a park in St Cloud.

I lost a collection of vintage coins while walking my dog in the park near St Cloud. They were in a small black pouch with a zipper. The collection includes a few rare coins from the 1800s that I inherited from my grandfather – they mean a lot to me personally. If anyone finds them, I would greatly appreciate if you could contact me.
