The 1917 Standing Liberty Quarter was minted with a bare breast and with a mailed breast with stars below the eagle. The modification was to cover Liberty's exposed breast. - .
Your quarter is almost certainly from 1917, not 1927, because the 3-star design was only used for the first year and a half of the coin's issue. Please see the Related Question.
The Standing Liberty Quarter was minted from 1916 through 1930. Each coin has its own value based upon its date, its mint mark and it condition. Please post a new question giving as much of this information as you can. For 1917 coins you also have to know whether there are stars below the eagle or not. The date is below Miss Liberty's feet, and the mint mark, if there is one, is on the left side of the coin at the bottom of the pillar with the words IN GOD on it. It may be blank, or there may be a D or S. The M on the other side is not a mint mark, it's the designer's monogram. If you can't read the date (a common problem with SL quarters) it's only worth its silver value, about $3.25 as of 05.2010.
All 1917 US "pennies" are called Lincoln Cents. The last Liberty Head Cents were minted in 1857, and nearly ALL modern US coins carry the word LIBERTY on them. Please see the Related Question for more information.
The 1917 Standing Liberty Quarter is a fairly common date coin but has two different types for that year. For an accurate assessment of value the coin needs to be seen as to what type it is and graded. I will list values for the most common of the two types. Most coins of this type have seen heavy use and show a lot of wear. In general retail values for low grade coins are $18.00-$25.00, better grade are $30.00-$56.00 and coins showing almost no wear run from $88.00-$126.00. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched or have been cleaned have far less value if any to a collector or dealer

A circulated Philadelphia issue type 1 is valued from $20.00 to $200.00 depending on the actual grade of the coin. Without more information, this is the best answer.
The best you can guess at is if the coin has 3 stars under the eagle on the reverse it was made from 1917-1930, no stars 1916-1917.

This type of quarter was designed by Hermon A. MacNeil. The left arm of Liberty is upraised uncovering a shield in the attitude of protection. Her right hand bears the olive branch of peace. There was a modification in 1917 because of public resentment to Liberty's exposed breast. The reverse is an arrangement of the stars and eagle.
1917 makes it a Standing Liberty quarter, so the mint mark is just above and to the left of the date (the mint mark on quarters wouldn't return to the obverse again until 1968). No mark indicates Philadelphia, S is San Francisco, and D is Denver.
