It's still worth one dollar.
The U.S. Mint does not issue painted coins. The value of one which has been painted is based on the value of the silver in the coin which varies day to day.
A 1999 American Eagle gold bullion coin is 1/4 ounce of pure gold, the value goes up and down with the spot price of gold during market trading. As of 10:05am 3-17-11 value is $350.20
Painting adds no additional value to the coin. It is still a bullion coin and most of its value is in the silver it contains. The value of the silver changes almost daily. Currently it is about $17.
1999 wasn't a really rare issue of the American Silver Eagle bullion coins. Depending on condition, you can most likely add a dollar or two to the value of silver contained in the coin. At the time of writing, sight unseen, I would estimate it to be worth around $30 depending on the grade with the bulk of that value coming from the 1 ounce of silver the coin is made with.
Face value only.
As of 06/2014 it has no added value, even in uncirculated condition.
No such coin like this exists. In 1999 the only small dollar produced by the US was the Susan B. Anthony dollar which was the same colour and compositon as the quarter. The Sacajawea dollar would first be struck dated 2000. If you indeed have a 1999 Susan B. Anthony coin, it is only worth face value unless in mint packaging.
