Gold is an easy way of protecting yourself for the fall of the monetary system. Gold bullion coins is the most recognized way of doing so. I recommend Krugerrands and Maples.
Canadian Gold Maple Leafs are minted by the Royal Canadian Mint, and picture a maple leaf and ist 0.9999, one of the purest gold bullion coins.
Krugerrands are minted by the South African Mint and are the best known gold coins. They feature an antelope and a more orange color due to the high amount of copper (their purity is the lower than Maples, .9167), which also makes them harder and less likely to be scratched. The copper also makes them weight more 33.93 grams (1.09 troy oz) and be larger that other purer gold coins.
With the state of the monetary base and the central banks' balance sheets, being a goldbug is not a choice anymore.
