saw this ‘72 Kennedy and did a double take as it appeared Kennedy was resembling the Emperor in Star Wars or The Thing. Lines looking like wrinkles covered much of his face. But if I looked at him again he appeared normal and youthful. But angle the coin and the “cracks” return. It reminds me of taking glass marbles and heating them up before dropping in cold water. They developed a network of fine cracks. So what gives here? Anything worth keeping?
