1981年350元。黄铜样币。三轮盘。青铜器出土文物。I 版。春秋三轮青铜盘。极罕版别，独一无二的样币版。我们首次上拍此非凡系列。NGC 仅鑑定过此枚，PCGS 无记录。此设计最终未被採纳。浮雕效果出色，Gem 级珍藏品。镜面底版全无斑点或起雾，与图文形成鲜明对比。

CHINA. Brass 350 Yuan Pattern, 1981. NGC PROOF-69 Ultra Cameo.KM-Unlisted. Diameter: 27mm. Bronze Age Discoveries. Type I. Three wheel plate. An EXTREMELY RARE and quite possibly UNIQUE 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. The cameo nature on this superb, stunning Gem radiates with great contrast, the fields being free from any spotting or haziness.
