Gold and silver prices are falling as the U.S. dollar continues to appreciate against other currencies, especially the Japanese yen.

Gold for June delivery lost $32 to $1,436.60 an ounce Friday. It's down 14 percent so far this year.

Silver also fell. The July contract lost 25.3 cents to settle at $23.658 an ounce. Platinum and palladium also dropped, while copper edged higher.

Gold led metals prices lower as the dollar strengthened against other currencies. The dollar has risen sharply against the yen after Japan's central bank announced an aggressive economic stimulus policy that involves flooding the country's financial system with cash.

The dollar traded above 100 yen Thursday for the first time in four years. It rose to 101.53 yen Friday.

Energy prices and grains and beans ended lower.
