All investments involve risk - coins and bullion are no exception. The value of a bullion coin (e.g. Maple Leaf or American Eagle) is affected by many economic circumstances, including the current market price of bullion, the perceive3d scarcity of the coins and other factors. Some of these factors include the quality, current demand and general market sentiment. Therefore, because both bullion and coins can go down as well as up in value, investing in them may not be suitable for everyone. Since all investments, including bullion and coins, can decline in value, you should understand them well, and have adequate cash reserves and disposable income before considering a bullion or coin investment.
