Vintage 1982 US Mint proof coin set, red case

I lost my vintage 1982 US Mint proof coin set yesterday around 3pm near the LSU Bookstore on Highland Road, by the campus loop. It's stored in a red hinged presentation box with a gold label and contains a slim black plastic display case with six coins that have a mirror finish. The inner velvet insert has a small "AP" handwritten initials in black marker on the inside lid, and the outer box shows light wear from being tucked in my backpack. This set was a gift from my grandfather and has sentimental value; I really need it back. If anyone found it, please reach out — I’d be forever grateful.
