Levi’s 505 Jeans (not original button/zipper) 33x32

Men’s Levi’s denim jeans, care tags have been cut, button and zipper seem to have been replaced, please note dent in replacement button. Denim is thick and study, but pants are in worn condition with some small holes and wear in the crotch near hem and at the ankles, see photos. I did not detect a smoke odor but the home they were purchased from may have a dog. Jeans were washed after purchase! Inseam measures 30” by my tape measure and waist measures about 16.5” when laid flat.
