NEW YORK—After falling 6 percent in the past three weeks, the U.S. dollar hit a 208-year low against the U.S. quarter, which had been valued at exactly 0.25 dollars since its introduction in 1796. "The dollar continues to slide against most major currencies," Morgan Stanley analyst Richard Jemison said. "At the end of the day Tuesday, the quarter was trading at .267 yen, .203 euros, and US$0.28. But what we're really seeing here is not just a dollar weakened by a sluggish economy, but an exceptionally resilient quarter-dollar." Jemison was quick to point out that the dollar remains very strong against the nickel.
