George I gold Half Guinea 1725, S-3637, 2nd Bust, MS65 NGC, a virtually perfect coin of mesmerizing beauty -- possibly the finest half-guinea this cataloguer has seen -- with a 100% full strike on each side (but no doubling of strike), perfect centering, high dished rims, intense luster, flawless surfaces, and exquisite sun-gold toning.
