NEW YORK, SEPT. 23 -- The dollar finished higher against most key currencies today in light to moderate trading, buttressed by expectations for the upcoming meeting of finance ministers of the seven major industrialized countries.

Gold prices edged higher. Republic National Bank of New York quoted a bid price for gold bullion at $462 a troy ounce, up slightly from $461.50 an ounce at the same time Tuesday.

Traders said the dollar was lifted by investors' purchases of the currency in advance of the meeting this weekend in Washington of the Group of Seven finance ministers.

"People really don't figure anything bearish {for the dollar} is going to come out of that meeting," said Jack Annunziato, a corporate trader for investment firm Prudential-Bache Securities Inc.

In Tokyo, financial markets were closed for a national holiday. In London, the dollar closed at 143.75 Japanese yen, up from 143.53 yen in Tokyo late Tuesday. In New York, the dollar was quoted at 143.95 yen, down from 144.35 yen late Tuesday.

The British pound fell in London for the third straight day, to $1.6425 from $1.6440 late Tuesday. In New York, the pound stood at $1.6425, little changed from $1.6423 Tuesday.
