These are raised lines so that can't be scratches on the working hub.  Perhaps you meant the working die?  But scratching the recessed
features in the working die would be deliberated efforts, not careless cleaning by the workers.  I compared these lines to striation
lines found frequently in the Historical Figures and the lines are significantly wider and higher than striation lines.  It is a
puzzling phenomena.
