Investing in Political Discussions Posted July 13, 2017 6 hours ago, Gehringer_2 said: 100 kg coin is just a silly thing to do. Of course having how ever many tons of gold are still sitting at Ft Knox is silly too. I think it was more a display of engineering and metallurgy skill then it was to fill a practical need. The production perfection of a coin that size had never been done before. The Canadian mint prides themselves on the superior production and refining of their Gold Maple Leaf coin. As impractical as the 100 kilo coin is, it was produced more as a bit of showing off by the Canadian Mint. Hence the quote at the end of the article by the Canadian Mint when asked why the coins were made, "Because we can." I would have to look it up but I think those coins were made about 20 yrs ago and no other refiner or mint has produced one since. The dificulty comes in the pouring of the metal also called the casting process. All the smaller 1 oz coins, wether American, Canadian, Australian etc.. are made from a stamping which is infinitely easier to do and control.
