What is the value of a 1973 roosevelt dime with no mint mark?

A 1973 Roosevelt dime without a mint mark is typically worth its face value of 10 cents, as it was produced in large quantities and is not considered rare. However, if it's in uncirculated condition or has unique characteristics, it could be worth slightly more to collectors, generally around 25 to 50 cents. Always consider having it appraised by a professional for a more accurate valuation based on its condition.
