Here’s a clever little error coin. I’ve never seen one like it…I assume it is a grease filled die on the last digit but it’s surprising that the “damage” is so acute. Any insights would be appreciated. Enjoy!
I have a very similar example. I also thought the digit got clogged with gunk. The presence of VDB narrows your coin down to just a few possible years, or it is really the rare 191 VDB.
