    Incredibly Elusive Inventions & Discoveries Set - The First We Have Seen

    People's Republic 2-Piece Certified gold & silver "Yin & Yang Philosophy" Proof Set 1993 Ultra Cameo NGC,
    1) silver 50 Yuan (5 oz) - PR68, KM507, Cheng-pg. 136, 1, CC-478. Mintage: 1000.
    2) gold 500 Yuan (5 oz) - PR69, KM509, Cheng-pg. 137, 1, CC-474. Mintage: 99.

    Shenyang mint. Inventions & Discoveries - Series II. An extremely rare Proof set that is simply never encountered on the market, with examples of the silver 50 Yuan seldom becoming available, and the 500 Yuan proving even more elusive--we have not been able to locate a single example coming to auction in the past 15 years. Each piece is rather lavishly struck and preserved, neither type having yet been awarded with the coveted PR70 designation in the NGC census, and the 500 Yuan tied for the finest certified by that company. We note that that while the mintage figures in both the Standard Catalog of World Coins and on the Certificate of Authenticity for the 50 Yuan state that 1000 pieces were struck, the Gold & Silver Coins of China Standard Catalogue maintains that only 803 were actually struck. The set comes sold with its original wooden presentation case and COA's numbered 491 and 45, respectively.


    1993年「中國古代科技發明發現 - 太極圖」精製金銀幣。一組兩枚。Ultra Cameo NGC。
    1) 50元銀幣 (5 盎司) - PR68 發行量1000枚。
    2) 500元金幣 (5 盎司) - PR69 發行量99枚。

    沈陽造幣廠。中國古代科技發明發現第二組。極為罕見的精製幣套裝,在市場上從未見過,50元銀幣很少出現,而500元金幣更是鳳毛鱗角,在過去15年中,我們從未在拍賣會上找到她的身影。鑄打精美深刻、保存完好,兩枚皆未能在NGC評級中獲得夢寐以求的最高PR70等級,唯500元的一枚暫時評得了最高分。 我們注意到雖然《世界硬幣標準目錄》和50元證書上均標示造幣數量為1000枚,但《中國金銀幣標準目錄》卻認為實際只鑄造了803枚 。 該套裝隨其原始木盒一起出售,證書編號為491和45。
