S-H4; KM-940.1. Weight: 3.3 gms. The normal shape of this piece being octagonal, this exceptionally stunning mint error immediately pops for being struck on a circular planchet obviously meant for a different piece. Nearly 10 grams lighted than intended, this dramatic piece is certainly RARE and enticing.
