The security offered by bullion is provided by its very independence.
Bullion is independent of states, currencies, productivity, credit worthiness and such.
Economic and political factors might influence the price of bullion, but its value and its acceptability remain independent of them. Experience has shown that the regular purchase of bullion coins helps to protect the smaller investor against price fluctuations. Over the years precious metals have proven to be one of the most reliable stores of value. Despite possible price fluctuations on the open market, the value of bullion has remained remarkably stable and has shown repeatedly the tendency to rise. With gold, platinum and silver coinage you possess an international currency which can always be sold around the world at any time.
