Bullion is the term investors use for your everyday coinage or bars. There are generally metals that are allowed into an IRA and the rise and fall with the market spot price, they won’t hold any intrinsic value. Investors can purchase bullion in rounds or bars. Bullion gets its value from its weight and the current spot price of the metal. Because of this, the value of bullion investments fluctuates daily, depending on global market values of gold, silver, copper etc. While you can invest in bars, the most popular coins are the Canadian Maple Leaf, the South African Krugerrand, and the American Gold Eagle.
