1.此幣種個人前後收集98枚皆為不同版.有相當證據證明當初上海造幣廠一版樣幣鋼模只造一枚樣幣.至於手中另有一版一枚費城造幣廠造鎳樣幣截圖保留暫不貼出.
2.此幣種正值減色降重的錢幣歷史.造幣的幣胚合金成色比例是如何?幣胚究竟是由費城造幣廠或是上海造幣廠製備.留待有心人繼續揭秘.
3.此幣種在正反兩面相同位置都設有共同防偽暗記.只要掌握此項特徵只需幾秒時間就能辨識錢幣真假.因此不管還有多少不同版別樣幣存世.辨識其真假也是易如反掌折枝.
4.造幣廠刻模技師的職責就是刻製造幣鋼模.並不存在沿用舊模及修模之說.如有需要必定是重刻造幣鋼模.
5.中國清朝時期造幣機器設備是向列強採購.也多委由列強刻製造幣樣幣鋼模.造幣受制於列強的憂患意識逼得清政府不得不著重本身造幣廠加強造幣防偽設計及自行刻製造幣鋼模的實力.因此現今對於當初委外承造樣幣與清政府自造樣幣的真假辨識就需要相當的實力.
1. The 98 coins collected by the individual before and after this currency are all different versions. There is considerable evidence to prove that the first version of the Shanghai Mint's sample steel mold only made one sample coin. As for the other version, a Philadelphia mint made nickel sample coin Screenshots will not be posted for the time being.
2. This currency is the history of coins that reduce color and weight. What is the color ratio of coin mint alloys? Is the coin embryo prepared by the Philadelphia Mint or the Shanghai Mint. It is left to those who are interested to continue to reveal.
3. This currency has a common anti-counterfeiting secret in the same position on both sides of the coin. As long as you master this feature, it can take only a few seconds to identify the authenticity of the coin. So no matter how many different versions of the coin exist in the world. Identify its true Fake is also easy to fold.
4. The duty of the mint carving technician is to engrave the coin steel mould. There is no such thing as using the old mould and repairing the mould. If necessary, it is necessary to re-engrave the coin steel mould.
5. During the Qing dynasty in China, the coinage machinery and equipment were purchased from the powers. Many commissions also made steel molds for sample coins from the powers. The mint was constrained by the powers of the great powers. The Qing government had to focus on its own mint to strengthen the anti-counterfeiting design and engrave itself The strength of manufacturing coin steel molds. Therefore, today it requires considerable strength to identify the authenticity of the outsourced sample coins and the Qing government's self-made sample coins.
