Another 2017-D LSC With Reverse Issue

Note on the "OF'. See how the devices are very wide. So the deeper portion of the die is filled. It may have been fresh grease, and after the first strike it splashed out of these deeper devices. Thus the surface of the fields received a coating preventing the strike to happen even on the fields. But until the dies are wiped down to remove it, there will still be the issue untill all the grease if spread to the coins struck. Then it will be back to normal on the fields again. But the filled devices will continue to be an issue until they are cleaned out.

Thank all of you for your input and comments. I just ran across another one but it is not as prominent as the original one.
