What is the value of a 1899 US dollar coin?

Assuming the coin is circulated and has no mintmark, the 1899 Morgan is a better date coin. For an accurate assessment of value the coin needs to be seen and graded. In general retail values for low grade coins are $98.00-$140.00, better grade are $160.00-$185.00 and coins showing almost no wear run from $195.00-$250.00. 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.
