For all Standing liberty quarters the "M" you see is not a mintmark, it's the designer H. A. MacNeil's monogram, a mintmark on this series of coins is located on the left side next to the last star at the bottom, across from the "M".
Assuming the coin is circulated, the 1928 Standing Liberty quarter is a common date coin of the series. For an accurate assessment of value the coin needs to be seen and graded. Most coins have seen heavy use and show a lot of wear. In general retail values for low grade coins are $8.00-$15.00, better grade are $20.00-$35.00 and coins showing almost no wear in the AU grades, run from $50.00-$95.00. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewelry or have been cleaned have far less value if any to a collector or dealer.
