5.0 grams. A dramatic error, deeply cupped from the planchet being stuck on the die through multiple strikes. The first appearance is suggestive of simply a rather deep die cap, highly desirable in its own right. However, this coin includes two planchets fused together, essentially as "nested" caps, one within the other. Vibrant red luster with areas of fresh, bright zinc showing where the planchets were most stressed by the strikes. A delightful example, so thick that it required one of NGC's custom extra-thick holders to contain it. Superb eye appeal and grade.
