Also 100 years in the history of gold is nothing, if you pull back, every single time gold was used as currency it was eventually if not outright counterfeited and manipulated, it was the inconvenience of carrying gold around that directly led to the creation of fractional reserve banking, while one gold vein or even a gold cache, if they be discovered, could bring the entire value of gold into the dirt, it's no better than any other commodity, except that you can't use gold for much of anything when it comes to industry while most commodities have an intrinsic utilitarian value outside valuation itself.
