That reminds me. Jeff Goldblum has his series on Disney+ "The World According to Jeff Goldblum". In one of the episodes he explores the world of Denim. One of the Segments of that show he goes and meets with a Denim Hunter who goes to abandoned Gold Mines looking for outfits from that era. Apparently there is a big collectors market for restored Denim from the Gold Rush period. They went on a hunt together for the show and actually found a pair of denim pants. I think he said he would be able to restore and sell the, for like $3000. It seems a little nutty.
