What is a 1858 half dime worth?

Assuming the coin is circulated and has no mintmark, the 1858 Liberty Seated Half Dime is a very common high mintage coin of the series. 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 $15.00-30.00, better grade are $35.00-$60.00 and coins showing almost no wear run from $75.00-$130.00. 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.
