This1942 D Mercury Dime is a valuable coin for collectors, featuring a high level of brilliance and potentially being at a mid mint state. This uncirculated coin has a 90% silver and 10% copper composition. It is 17.9 mm in diameter and weighs 2.5 grams. It is a business strike from the Denver mint. 

This is an excellent, uncirculated Mercury Dime that appears to be in mid mint state condition.  I placed it in the coin flip to protect it.  Please see the photos to assess its overall excellent condition. 

With its iconic Mercury design and historical significance, this dime is a prized addition to any numismatic collection.
