It's probably debris or a stain on top of the regular surface of the coin.
Perhaps this dime was sitting between two other dimes and some contaminant landed on both sides.
If this was a straight line on just one side, my guess would be a stain from a rubber band decay.

Some type of environmental stain/corrosion... PMD. Cheers, RickO
