Oil was $12.21 a barrel in 1975 and a one ounce gold coin was about $150. So that coin would buy you 12 barrels. Today gold is $830 an ounce and oil is $115. So an ounce of gold will buy you 7 barrels. So if you kept your money in dollars since 1975, you will have lost 940% of your oil buying power. If you'd have kept it in gold, you will have lost 171% of your oil buying power. But gold hasn't changed much in value. It's more like oil went up a little and the value of the dollar dropped through the floor.
