RTTNews - Gold prices edged lower on Monday, giving back its gains from last week. A sharp drop in crude oil prices led a broad decline for commodities.

December-stamped gold settled at $952.20 an ounce, down $5.30 on the session. Prices touched as low as $944.30 earlier in the session after hitting as high as $962.10.

The dollar moved slightly lower amid uncertain trading against the euro, giving back some of its recent gains. The buck also weakened against the British pound. Gold usually moves opposite the dollar because of the precious metal's hedge appeal.

Crude oil plunged to $69.96 per barrel, down $2.78 on the sessions. Oil had hit as high as $75 a barrel last week.

In economic news, the ISM - Chicago said its index of manufacturing activity rose to 50.0 in August from 43.4 in July. Economists had been expecting a more modest increase to a reading of 48.0.
