1904 10C MS66+ Certification #06666239, PCGS #4833
The 1904 Dime is a common date thanks to a hefty mintage of over 14 million pieces. Most examples are well struck and of the high quality normally associated with the Philadelphia Mint. In some cases, dies were used beyond life expectancy, and some coins struck from those dies exhibit weakness on Liberty's upper lip, and the lettering and devices on the reverse have a mushy, rounded appearance. Some examples show clashing, as well.
