Assuming the coin is circulated and has no mintmark, the 1899 Morgan dollar is a better date of the series. For an accurate assessment of value the coin needs to be seen and graded. Most coins of this year have seen heavy use and show a lot of wear. In general retail values for low grade coins are $98.00-$140.00, better grade are $160.00-$175.00 and coins showing almost no wear run from $190.00-$240.00. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewlery or have been cleaned have far less value if any to a collector or dealer.
