CAC. High R-7. Fewer than a half dozen known. William Barber’s Seated Liberty design depicts Liberty facing left. The reverse is the regular Seated Liberty Half Dollar die. Struck in aluminum with a reeded edge. This is a sharply struck proof with strong cameo contrast between reflective fields and frosted devices. Deep, mirrorlike surfaces show excellent clarity, while Liberty and the eagle display crisp, intricate detail. Well-preserved with minimal handling marks, offering outstanding eye appeal for this rare issue.
