George IV gold £2 1823, S-3798, KM690, one-year curly haired portrait type, "Unc Details Surface Hairlines" NGC. The hairlines seem trivial, the luster remains satiny and intense, the strike is bold, only light abrasions appear on the surfaces (other than the hairlines), and the color is a lovely golden orange in hue.
