The "M" that you see is the designer, Hermon MacNeil's monogram and is on all Standing Liberty quarters the Mintmark (if any) is to the left of the date. Assuming the coin is circulated, the 1927 is a fairly common date of the series. For an accurate assessment of value the coin needs to be seen and graded. Most coins of this type have seen heavy use and show a lot of wear. In general retail values for low grade coins are $7.00-$9.00, better grade are $12.00-$32.00 and coins showing almost no wear run from $65.00-$105.00. 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

August 1, 2009 The US Mint has not issued a quarter with an "M" stamped on it. Probably what you have is a quarter that someone has put their initial on or marked it for some reason. With such a mark it has no numismatic value but is worth $2.52 for the silver it contains.
