1900 is a common date for a Barber dime. 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 circulated coins (without a mintmark) are $3.00-$10.00. NOTE: Values are only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewelry or have been cleaned are only valued for the silver.
