United States one dollar bills are curled and inspected during production at the Bureau of Engraving and Printing in Washington.
The dollar index, which measures the currency against a basket of six major peers, including the euro and yen, was little changed at 103.02, after tracking between 103.75 and 102.75 since early June.
The dollar hovered about half a yen below the 145 level that spurred intervention by Japanese authorities last autumn, after last week briefly popping as high as 145.07 for the first time since November.
Australia's dollar was flat at $0.6690, holding on to the previous day's 0.32% advance.
The yuan was little changed at 7.231 per dollar in offshore trading, following a 0.3% rise on Tuesday as it continued its rebound from last week's eight-month low of 7.2857.
