Many choose to protect their wealth by adding bullion to their portfolios due to its historical growth and the overall stability of gold and silver. Additionally, bullion coins can be purchased at a price much closer to the spot price of gold, because you are not paying a premium for additional numismatic value, as with private coins.
It is important to note however, that bullion cannot be purchased at the exact spot price, even though the spot price determines its value. This is due to the cost of bringing the product to market. The spot price is only the starting price before extraction, minting, certification, etc.
