Raised lines?

Hi, 

Sure this is common, but don't have it on any of my other pennies (that I can see). Slightly raised lines are they die polishing lines?

Any information very welcome as always.

Parallel straight raised lines are indicative of die polishing. Single non-linear lines are more likely to be cracks in the die surface as it starts to break up.
