I had this exact same Levi’s belt. Had it for about 15 years. The other end with the holes is the end that gets dirty and damaged. My belt still worked and I loved it but it looked beaten up. It was warped a lot at the hole end and it was badly discolored. Not only did it warp out where the buckle was but it had also sheared so if you lay it down flat it curved up at the end rather than being a straight line.

It was a great belt but definitely needed replacing after 15 years.
