Copper key fob with dog charm

I lost a tiny copper key fob with a little enamel beagle dog charm and my initials 'MR' etched on the back. It's about the size of a quarter, with a warm copper patina and a small thread loop for attaching to a keyring. I last had it yesterday around 3pm near the Fredericksburg Public Library on Caroline Street, after grabbing coffee from a shop nearby and waiting for a friend. The charm is sentimental—my grandmother gave me the key to her old garden shed, and I really need it back. If anyone found it, please drop me a message; I’d be forever grateful.
