Bernanke has pushed interest rates to near zero since the 18-month recession that began in December 2007. The Fed said in March it would continue buying $85 billion in securities each month in a program known as quantitative easing that has ballooned its assets beyond $3 trillion and is aimed at keeping long-term borrowing costs low to support economic growth.

Consumer prices rose just 1.3 percent in February from a year earlier, according to an inflation measure favored by the Fed. That was below the central bank's 2 percent target and compares with occasional bouts of more-than 10 percent increases in the 1970s and early 1980s.

Bets that inflation would pick up because of economic stimulus measures helped fuel a 78 percent jump in gold since December 2008. The dollar's rise to less than 1 percent below a one-year high set in July and monthly increases of about 2 percent or less in the U.S. consumer price index have curbed demand for bullion. Since reaching a record $1,923.70 an ounce in 2011, gold prices have fallen and are near a bear market.

Gold futures for June delivery fell 1.2 percent last week, to $1,575.90 an ounce on the Comex in New York, after touching $1,539.40 April 4, a 10-month low for a most-active contract.

Texas Depository

In Texas, lawmakers are considering a measure supported by Republican Governor Rick Perry to establish the Texas Bullion Depository to store gold bars valued at about $1 billion and held in a New York bank warehouse. The gold is owned by the University of Texas Investment Management Co., or Utimco, which took delivery of 6,643 bars of the precious metal in 2011 amid concern that demand for it would overwhelm supply.

The proposed facility would also accept deposits from the public, and would provide a basis for a payments system in the state in the event of a “systemic dislocation in a national and international financial system,” according to the measure.

Should Texas take such a step, it would offer sovereign backing for deposits and make buying and storing gold easier, said Jim Rickards, senior managing director at Tangent Capital Partners LLC in New York and author of “Currency Wars: The Making of the Next Global Crisis.” He said the coin measures, while impractical, have symbolic value.

“We are seeing a distinct movement back to a world where gold is considered money,” Rickards said.

The measures give “people the option of using money that won't lose any purchasing power to inflation,” said Rich Danker, economics director at the American Principles Project. The Washington-based public-policy group supports the steps as well as a return to the gold standard, which pegged the dollar's value to bullion. President Richard Nixon formally ended the convertibility of U.S. currency to the precious metal in 1971.

“People in these states find the idea of having the option to use hard currencies appealing over these policies they have no control over,” Danker said.

The U.S. Constitution bars states from coining money and also forbids them from making anything except gold and silver coin tender for paying debts. Advocates say that opens the door for the states to allow bullion as legal tender. The measure being considered in South Carolina would recognize foreign or domestic minted coins as legal tender.

Utah's law applies only to U.S.-minted coins, while other states are less clear on whether privately produced coins qualify. Arizona leaves the door open for private coins if they are declared legal by a non-appealable court order.

Tax Breaks

In Utah and some other states, the measures also eliminate state capital gains or other taxes on the coins.

Critics say the state measures are unwieldy. In Arizona, Senator Steve Farley, a Democrat, unsuccessfully offered an amendment that would have recognized as legal tender other state commodities, such as citrus fruit, as well as sunbeams. The amendment was intended to reflect the absurdity of the bill, said the 50-year-old lawmaker from Tucson.

“It is simply grandstanding to get people afraid that somehow President Obama's agenda is going to drive us into hyperinflation and economic collapse,” Farley said. “We have enough real problems to deal with. I don't see undercutting our entire financial structure as a priority.”

In Utah, officials haven't yet figured out how to accept gold and silver for tax payments — though some residents have asked to pay that way — or integrate the precious metals into commerce, state Treasurer Richard Ellis said. Lawmakers have established a task force to study implementing the law and to examine how the state can accept gold and silver, with their fluctuating values, for payment, Ellis said. He's not optimistic that it will work, he said.

“People point to Utah and say we are leading the way, but nothing much has happened because regulatory hurdles have gotten in the way,” said Ellis, a Republican. If gold and silver is being used in the state as legal tender, it is probably only in transactions between individuals, he said.

The Utah Precious Metals Association, established after passage of the 2011 law to advocate for the use of gold and silver coins, has about two dozen members enrolled in a two month-old bill-pay service in which their accounts are held in gold, said Lawrence Hilton, the group's chairman. Hilton envisions a future with an alternative monetary system based on precious metals in which merchants accept silver coin while gold mostly backs electronic transfers.

Arizona measure, sponsored by Republicans, won preliminary approval in the House of Representatives April 4 after passing the Senate on a party line vote Feb. 28. Gold is mined in both Arizona and Utah, while Nevada is the largest U.S. producer, according to National Mining Association figures.

The bill's sponsor, Senator Chester Crandell, 66 of Heber, said he is convinced the move is the “logical thing for the state of Arizona to do.”

“I think you look at some of the things that are happening and the amount of money printed by the Federal Reserve and who has control of that money, and I think anybody would be concerned,” Crandell said. “Gold and silver have been around a long time and people are secure with it and we should give them an opportunity to use it.”
