Rarity: The 1964 dime is considered common as it was widely produced before the transition to copper-nickel clad dimes in 1965.
Condition: A dime's condition significantly impacts its value. Coins in better condition command higher prices.
Grades: Common coin grades include Poor (P), Fair (F), Very Good (VG), Fine (F), Very Fine (VF), Extremely Fine (EF or XF), and Mint State (MS).
Uncirculated coins: Uncirculated 1964 dimes that have not been used for commerce tend to have higher values.
Full Bands: The presence of full bands on the reverse torch (on the fasces) enhances the value for mint state coins.
Mint set coins: 1964 dimes from mint sets can sometimes be more valuable than those found in circulation.
Errors and varieties: Certain minting errors or die varieties can increase the dime's value, such as double dies or striking errors.
Grading services: Coins authenticated and graded by reputable services like PCGS or NGC often have a higher value.
Bullion vs. collector value: Some people collect these dimes for their silver content, while others focus on their numismatic value.
