. February 11, 2007 SouthAmerica: When I saw the enclosed article I immediately thought â the US is going to release a new US dollar â then a saw the word coin. But for a second I thought the US dollar has lost so much value that it might be a good idea to follow the lead of countries such as Brazil. Over the years I remember the Brazilian currency changing many times from âCruzeiroâ, to âNew Cruzeiroâ, then to âCruzadoâ, and to âNew Cruzadoâ, then came the âCruz Credoâ and finally the âRealâ. Today there are so many US dollars flying around the world that might be a good idea for the United States government to replace its current US dollar with the âNew US Dollarâ â and the new exchange rate would be: each current $ 100 US dollar would be exchanged to $ 1 New US dollar. â Just like they usually do in 3rd world countries when their currency starts becoming worthless. A house that was bought in our area in Northern New Jersey in the early 1950âs for US$ 4,000 dollars â the same house is worth today in the range of US$ 400,000 to US$ 500,000. The exchange rate of $100 âOld dollarsâ to $1 âNew Dollarâ would be just about right. ******* âU.S. gov't to release new dollar coinsâ By WILL LESTER, Associated Press Writer AP â Associated Press Sun Feb 11, 2007 WASHINGTON - Two recent efforts to promote wide usage of a dollar coin proved unsuccessful. But maybe Susan B. Anthony and Sacagawea should not take public rejection personally. It's not easy overcoming people's indifference to dollar coins, even those honoring such historic figures. An AP-Ipsos poll found that three-fourths of people surveyed oppose replacing the dollar bill, featuring George Washington, with a dollar coin. People are split evenly on the idea of having both a dollar bill and a dollar coin. A new version of the coin, paying tribute to American presidents, goes into general circulation Thursday. Even though doing away with the bill could save hundreds of millions of dollars each year in printing costs, there is no plan to scrap the bill in favor of the more durable coin. "I really don't see any use for it," Larry Ashbaugh, a retiree from Bristolville, Ohio, said of the dollar coin. "We tried it before. It didn't fly." A quarter-century ago, the dollar coin showed feminist Susan B. Anthony on the front; then one in 2000 featuring Sacagawea, the Shoshone Indian who helped guide the Lewis and Clark expedition. The latest dollar coin will bear Washington's image, followed later this year by those of John Adams, Thomas Jefferson and James Madison. A different president will appear on the golden dollar coins every three months. People have strong feelings about their money, even the penny, which occasionally is threatened with elimination. When people were asked whether the penny should be eliminated, 71 percent said no, according to the poll of 1,000 adults conducted Nov. 28-30 that had a margin of sampling error of plus or minus 3 percentage points. Some fear that getting rid of the penny will cause product prices to be rounded up, perhaps increasing inflation. .
