So did the German Mark after The Great War of 1914...WW I. After the treaty was signed. their paper currency was essentially worthless. The German people who had gold and silver coins in their possession were able to purchase goods without the tacked on inflation of their now worthless Marks. The resulting economic upheaval led eventually to the election of a leader who promised the German people a strong economy and military...we all know how well that one turned out. Zimbabwe, formerly Rhodesia, has issued TRILLION DOLLAR banknotes....Fiat currency is only as valuable as the government issuing it says it is....in 1929, a U.S. $20 gold double eagle would buy a custom tailored suit...in 2015, it still will. 90% Silver was taken out of most U.S. coins beginning in 1965...replaced with clad coins...pennies are now essentially zinc with a copper plating...melt value is zero! I remember as a kid in 1964/1965 time period when Sherry Lewis, who had a children's program on television, and Lamb Chop, her little puppet, told kids to turn in their silver dimes, quarters and half dollars, due to a "coin shortage"...we were lied to...us kids!
Gas prices have dropped, but any realized savings are being used to pay down personal debt...too many folks using credit cards to purchase what they want, not what they need. Cards that can add 20% interest rates to the bottom line. My step-father passed away two years ago with over $67K in credit card debt....debt like that is recouped by the credit card companies using their ridiculous rates! Usury by individuals is illegal...not so banks and credit unions.
