A special 5-pound coin honoring Princess Diana goes on sale in Great Britain this Thursday, July 1, her birthday. The coin, worth about $8, features a portrait of her in profile. A portrait of her former mother-in-law, Queen Elizabeth II, is on the reverse side. Limited editions in gold and silver were sold earlier this year. All proceeds go to the charitable fund set up after Diana’s death in a Paris car crash in 1997.
