1873 3CS PR67CAM PCGS #83724

CAC - "This is a singularly beautiful Superb Gem specimen of this proof-only issue. At first glance, the rose and blue toning at the centers appears to be the lightest patina on the coin, but then at a different angle, the formerly "black" mirrors come to life with pale sea-green color."
