Seated Liberty Half Dollar. Only 625 proof half dollars were struck in 1867 and high grade Cameo examples are difficult to locate. In fact, NGC has only certified five other examples in PF-65 and three finer. This is a deeply reflective proof that shows lovely, multicolored toning over each side. The contrast between the fields and devices is apparent even through the multiple layers of color. The coin is fully struck in all areas.
