Navy queen duvet cover with white piping

I lost my navy blue queen-size duvet cover with white piping yesterday around 3pm near the Potsdam Public Library on Park Street. It's a SleepWell duvet cover, smooth cotton with a sturdy zipper, and there's a tiny coffee stain near the zipper pull. There's a SleepWell tag stitched in the bottom corner, and a faint heart outline you can only see when it's inside out. It was a gift from my grandmother, so it means a lot to me, and I'm really hoping to get it back. If you found it, please reach out.
