Drain pineapple, reserving juice. Place ham on a rack in a shallow roasting pan. Secure pineapple and cherries to ham with toothpicks. Combine brown sugar and seasoned salt; rub over ham. Gently pour pineapple juice over ham. Bake, uncovered, at 325° for 1 1/2 to 2 hours or until a meat thermometer reads 140° and ham is heated through. Baste frequently with brown sugar mixture.
