Expensive Item - But Free!

Out one day on a drive, we came across a house that was being gutted.  A mid-century home with these lovely beveled mirrored cabinets standing right out on the sidewalk.  Of course, we gently loaded them into the truck and home they went.  Then, coincidentally, I saw them in New York Magazine in an advertisement for an antique auction at a prestigious mid-century auction house! Estimated price:  $2,500 apiece.  I also have a larger table sized piece that's out in the laundry house.  Who throws away mid century jewels?
