the advantages of fractional gold? Flexibility and liquidity. That is, if and when the time comes to sell gold for cash, you can sell the unit of gold most reflective of your cash needs. You may only need $400 for an unexpected expense, so why sell a full ounce of gold for $2,000 when a gram or 3 makes more sense? For those of you who feel gold may someday be used as a currency for barter or trade, common sense tells us a smaller fractional gold bar may be more practical than the traditional one ounce bar. An analogy frequently used is that whereas a couple of grams of gold bars might yield an adequate amount of beef and milk in trade, the one ounce piece may force you to take the whole cow.
