What is a bullion issue?

[J.Cordeiro]

Precious metals in bulk form are known as bullion. The defining attribute of bullion is that it is valued by its mass and purity rather than by a face value as money.
For instance, Canada mints a gold bullion coin (the Gold Maple Leaf) at a face value of $50 containing 1 troy ounce (31.1035 g) of gold ? as of August 2007, this coin is worth about $667 as bullion.
