I know enough about coins and error coins just to be dangerous but I do try to improve. I'm guessing machine doubling but would appreciate comments from the learned members. There's other doubling in Liberty especially on the R and in "trust"which were hard to get decent pictures with a flashlight lens over a magnifying glass underneath my phone camera lens. I tried to enhance some of the pictures the best I could. Thank you for your time.
The mint mark was hand punched in to the die, so if you have the same movement in the mint mark and date it means machine doubling.
