All SBA dollars should have a mint mark above the point of her collar, on the coin's left side. They were struck at all 3 mints so you could see a P, D, or S.
Check that coin again. If it's dated 1896, then that's a Morgan dollar with an image of Liberty on the front. The Susan B. Anthony dollar wasn't introduced until 1979. The mint mark on a MORGAN dollar is on the reverse side, near the bottom, just above the letters "do" in the word "dollar."
The coin is a SACAGAWEA dollar NOT a S.B.A. dollar. 1999 was the last year for the S.B.A. coins. 2000 is the first year for the Sacagawea dollar. It's just a dollar, spend it.
Susan B. Anthony only appeared on $1 coins issued 1979-81 and 1999. Please don't assume EVERY woman on a U.S. coin is her. In fact, the vast majority of U.S. coins with a woman on them carry a picture of MISS LIBERTY, as in "Statue of ..."!!!!
About $20-30 retail. However, Susan B. Anthony dollars have next to no demand to collectors so I wouldn't be surprised if a coin shop isn't interested in buying it or gives you a low offer like $5 or so.
$1 to $7500 depending upon the mint mark, the variety and the condition of the coin.
On Susan B. Anthony dollars, the mint mark is on the front side, on the left, just above Anthony's right shoulder.
S is the mint mark for San Francisco.
With the date of 1979 the coin is a Susan B. Anthony Dollar, none contain any silver and most all are face value. The mint mark is on the obverse (front) of the coin above the left shoulder.
There was no 1999-O dollar minted. The O mint mark signified the New Orleans Mint, which closed down 90 years earlier. The only dollars minted by the US Mint were the Susan B. Anthony dollar, which contained no silver at all, and the American Silver Eagle, which contained roughly 1 oz. of silver.

It's the monogram of Anthony Di Francisci, the coin's designer.

By the mint mark on the reverse of the coin, but silver dollar coins with no mint mark are made in Philadelphia
