We've returned from the antique appraisal event. We decided at the last minute to take different items: a piece of Roseville pottery that my parents received as a wedding present and the original Herbert Fall oil painting of the Palmer Mill that hangs in our dining room. The pottery has "intrinsic value" (aka worthless). The painting, while having some monetary value, is priceless to us and of great interest to the appraiser for the story behind it and the frame (also probably handmade by the artist).
It was a very interesting day - we learned a lot and laughed a lot.
