I'm not certain which coin you are wanting to know about. In 1889 there were no coins to my knowledge called "liberty dollar". However, there was a gold dollar minted that year which was minted in Philadelphia and therefore carries no mint mark. None were minted anywhere else. Also in 1889 there was a silver dollar minted called "Morgan Dollar" . The mint mark on this one is located below the wreath on the reverse side of the coin. These were minted in Carson City, Nevada and carried a "CC" mint mark: New Orleans, Louisiana and carried an "O" mint mark: San Francisco, California and carried an "S" mint mark: Philadelphia, Pennsylvania and carried no mint mark at all.
No mint marking
The mint mark on a Morgan dollar (if any) will be found on the reverse of the coin under the wreath between the "D" and "O" in "DOLLAR".
The mint mark (if it has one) on all Morgan (1878-1904 & 1921) silver dollars is on the reverse of the coin, just above the letters "DO" in dollar.
1892 Liberty silver dollar mint mark in on the reverse just above and between the D and O in Dollar at the bottom of the coin. Mine is marked with an S.
The mint mark (if it has one) on all Morgan silver dollars is on the reverse of the coin just above the letters "DO" in dollar.
No mint marking
$27 to $350,000 depending upon the mint mark and the condition of the coin.

The current price of gold means that most 1889 double eagles are worth more for their metal than as collector's coins. Assuming average wear, it would sell for about $1100 regardless of mint mark. If you have a coin in almost-new condition AND it has a "CC" mint mark on the back, it does have a collector's value of up to $1900.
Please post a new question with the coin's date and mint mark.
