Like old used cloth or plastic (Naugahyde) guitar straps which sold new for $1-3, he wants up to $170. (I still have some of those cloth straps from the 60s that cost me $1.99 new)..
Put them on eBay hipsters and Blues Lawyers pay top dollar for those vintage straps. If you have a vintage amp and guitar, you need the period-correct strap to go with it.
