Who says a dollar doesn't go as far as it used to?
When it comes to dollar bills, a new report from the federal government says they're lasting more than twice as long as they were at the beginning of the decade.
And that's upending an old argument about replacing the dollar bill with a $1 coin.
Analysts have long argued that the federal government could save money by making the switch because even though coins cost more to mint, they last much longer than paper money. In 2011, the Government Accountability Office estimated the savings at $5.5 billion over 30 years.
