Brass stirrups
Whenever there’s a garage sale in your neighborhood, it won’t hurt to stop by and see what sort of fun stuff they have for sale. You’re helping your neighbor while also taking home an object that’s potentially worth a fortune. But to be real, you probably won’t find a diamond from all of the garbage they’re trying to unload.

This guy’s father came across a set of brass shoes, which the internet clarified were brass stirrups. It looks like these stirrups were frequently used at one point. You can see just how worn out one side of the stirrup is compared to the other.
