A
PBS show that travels to various cities and invites the locals to bring in their
antiques for a free
appraisal. Interesting pieces are appraised on camera, and the highlights are edited together to make an episode.
The appraiser will usually ask the owner, "Do you have a guess about how much this is worth?" and the owner is usually surprised to learn its true value. Sometimes that means that their silver spoon dates to the 1300s and is fantastically valuable; sometimes it means that they've spent $1000 on a reproduction.
