On a recent repeat episode of “Antiques Roadshow,” I caught a segment featuring a man with two 19th century paintings by J.F. Kensett that he’d purchased at a yard sale. He told the AR appraiser that he once had them appraised for $800-$900 by a woman who also offered a buyer for the paintings. The AR appraiser, after examining the paintings and consulting with colleagues, told the man a conservative auction estimate for the paintings was $30,000-$60,000 each. Understandably, the man was speechless. (A transcript of this exchange can be found at www.pbs.org/wgbh/roadshow/archive/200605A41.html) His is not the first story of this kind I’ve heard on the show. I always wonder how close these people came to accepting a first, and lesser, offer for their valuables and what must be going through their minds when they find out they were almost robbed of the true value.
