If it is a 501 until the early 1980s, the fabric with a redline is used, especially the one manufactured after the 66chain model is called "redline model". It used to be that you could see them in every thrift store. Because of their fading characteristics, denim is often not treated as vintage, but more and more people are preferring this kind of fading of denim and it is becoming more popular. According to the documents on Cone Mills, the company's facilities were modernized between 1975 and 1983, including the introduction of open-ended spinning. It is thought that the change of the spinning method has a great influence on the change of the color fading so much though it is woven on the same old loom.
