Judith Miller, the author of popular antiques price guides and a member of the team of appraisers who determined what was trash and what was treasure on “Antiques Roadshow,” the beloved long-running BBC program that inspired the American series of the same name, died on April 8 in North London. Once, Mr. Wainwright recalled, at the reception for his mother’s funeral, a woman approached Ms. Miller and pulled a plate out from under her coat, wondering what it might be worth. Ms. Miller’s books, updated regularly, are encyclopedic in their range and eclectic in their categories. They describe thousands of objects — the current antiques edition lists more than 8,000 — each illustrated by a sumptuous color photograph. There were the usual suspects, like Royal Doulton Art Deco teacups and saucers, Meissen pottery, Murano glass and pages of Scandinavian ceramics.
