Is this a common error? New to the coin world. I just started going through my Grandfathers coin collection. Is it worth anything...? Thoughts.. No E in pluribus unum
Welcome to CT!!! This is actually quite common. They grease the dies before use and whoever cleaned the excess grease off this die left a little too much in the E of EPU. So much grease that it caused the E not to show up on some coins like yours. Most of the time it add no value unless a lot of the devices are missing. Still a fun find though.
