I would like to know if these are rare and vintage. From what I’ve found i think these are Big E and 501xx selvedge, and from the things I’ve heard on internet these could potentially be pretty old? V stitch , an R on the button on the inside, chain stitching on the botom leg inside and so on. They also have no care tag or so which i guess indicates that they are not from a newer remake either. Please help me out!
