Levi's Original 501 Straight Leg Button Jeans USA 30 x 30 Vintage? Hi Rise?

I don't know what year these are from...I read that 501s that have a Made in USA tag were made before 2002 so vintage unless they are reissues but most reissues were made abroad?). I have no idea. The wash is darkish and has an orange tinge. (The first three photos are closest to actual color: some photos make jeans look lighter than they actually are). Stitching is burnt orange and lemon yellow (horiz. on coin pocket and arched on back pocket are yellow). There is "511" stamped on fly button. Jeans are in excellent condition, no stains or signs of wear on hem edges, back pockets, etc. Patch is a little faded and curled at edges. Inside pocket with Levi branded info. is a little faded but maybe printed that way. Care tag and other label is bright and clean. Waist: 29" Inseam: 29" Rise 10.5"
