Red general admission concert ticket

I lost my red general admission concert ticket yesterday around 3pm. It's a small white paper ticket with a bold red 'BMF' stamp and a scuffed corner, about the size of a business card, with the barcode at the bottom that's slightly smudged. There's a tiny coffee stain on the back and a small pen mark with the initials 'PR' near the edge. I had it in my pocket after grabbing coffee on Kirkwood Ave and walking past the Sample Gates near the IU campus in Bloomington. It means a lot to me - this was a gift from a friend who moved away, and I'm really hoping to get it back. If anyone's found it, I'd really appreciate getting it back.
