1981年350元黄铜样币。出土文物青铜器系列一。CHINA. Brass 350 Yuan Pattern, 1981. NGC PROOF-68 Ultra Cameo.直径：27毫米。青铜时代发现。第一型。马与燕子。此枚样币同样极为罕见，可能为世上仅存的孤品，出自同一系列非凡的样币设计，首次公开呈现。此枚为NGC唯一认证的同类样币，PCGS亦无相关记录。该设计最终未被採用。币面光彩夺目，璀璨生辉，仅反面铭文处有一处微小斑点，这或许是阻碍此枚珍品获得更高、近乎完美评级的唯一因素。KM-Unlisted. Diameter: 27mm. Bronze Age Discoveries. Type I. Horse & swallow. An <strong>EXTREMELY RARE</strong> 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. Just one minor spot on the reverse among the legend is likely what prevents this otherwise glistening, radiant Gem from an even higher, nearly-perfect designation.
