Lost two Taylor Swift concert tickets for section 104, row B, seats 12 and 13, last seen near Coffee Fury, Merced.

I lost two tickets to the Taylor Swift concert, section 104, row B, seats 12 and 13. I last remember having them when I was walking back to my car after hanging out with friends at Coffee Fury in Merced. I can't believe I misplaced them; they were in a navy blue envelope. If anyone finds them, I would be so grateful to get them back!
