Navy blue duvet cover set with white piping

I lost my navy blue duvet cover set with white piping yesterday around 6:30pm near the CVS on Main Street in Wellsboro, PA, in the Twin Tiers area. It's a Bedsure queen duvet cover set with 2 pillow shams, and the fabric is a bit faded and softened from use. There are two identifying details: a small coffee stain on the inside flap near the zipper, and a silver monogram 'AH' embroidered in the inner corner. This set has sentimental value, since it was a gift from my grandmother, and I would be really grateful to get it back.
