    Description

    People's Republic 10-Piece gold & silver Proof "Inventions and Discoveries" 5 & 100 Yuan Sets 1992,
    1) 5 & 100 Yuan - Ancient Shipbuilding, KM404 & KM415
    2) 5 & 100 Yuan - First Seismograph, KM405 & KM416
    3) 5 & 100 Yuan - First Kite, KM406 & KM417
    4) 5 & 100 Yuan - First Compass, KM407 & KM418
    5) 5 & 100 Yuan - Bronze Age Metal Working, KM408 & KM419

    Each coin remains sealed in the mint vinyl and included are the two original cases for both the gold and silver sets. The miniature replicas of the first compass are missing from both sets as are the COAs. The gold set is the much scarcer of the two, as 1000 pieces were produced of each type, but most sets have been broken up and many pieces have been melted.


    1992年中國古代科技發明發系列,5元和100元金銀幣精製幣一組10枚,
    1)5元和100元- 古代造船,KM404 & KM415;

    每枚均置於原包裝密封膠套,連原裝盒。不含指南針的小型複製品。金幣套裝特別稀有,因為每款發行量只有1000枚,但許多套已被打散,及多件已經被融化。

    The outcome of the auction far exceeded my best hopes and would not likely have been as successful with out your sound advice on where to present the coin and how best to set the reserve. Throughout the process your availability , support and knowledge were exceptional.
