Gold prices have been tied to talks in Washington on the so-called "fiscal cliff" which is the budget plan that would kick in Jan. 1 if a new budget compromise is not reached before then.
The gold market has lately been bullish on a fiscal cliff solution and bearish when talks stall or the chance of a compromise appears to be waning.
On Monday, gold gained $4.80 or 0.28 percent to close at $1,717.50 per troy ounce. Silver added 43 cents or 1.3 percent to reach $33.71.
The dollar index was dropped 0.41 percent to 79.90 in the International Exchange. The dollar fell to 82.20 yen from Friday's 82.48 yen. It was otherwise mixed in Asia.
