What is the value of a 1918S US dime?

Assuming the coin is circulated, the 1918-S Mercury Head dime is a fairly common coin. For an accurate assessment of value the coin needs to be seen and graded. Most coins show a lot of wear. In general retail values for low grade coins are $2.00-$5.00, better grade are $10.00-$30.00 and coins showing almost no wear run from $40.00-$60.00. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewelery or have been cleaned have far less value if any to a collector or dealer
