CHINA. Brass 350 Yuan Pattern, 1981. NGC PROOF-69 Ultra Cameo.KM-Unlisted. Diameter: 27mm. Bronze Age Discoveries. Type I. Square cauldron with human faces. An EXTREMELY RARE and quite possibly <strong>UNIQUE </strong>pattern issue that emanates from a remarkable series of such patterns that we are offering for the first time. This represents the only such example seen at NGC, with none having been seen at PCGS. This design was ultimately never utilized. Featuring a hint of deeper burnished bronze toning near the central portion of the frosted devices, this exceptionally mirrored specimen is free from any spotting or haze.
