Likely the result of the application of a rotary mechanical 'device' (agree with Tanman2001). Slightly larger rings on nickels typically indicate heavy use in rotary coin 'ingestion' devices--think old-school insert-and-twist parking meters and arcade machines.

Really nice closeup NYI. It does appear to be from an anomaly on the die.

Tanman was suggesting the effects on this coin was the result of die polishing.

Are you thinking this is PMD, like what might happen from those devices you mention?

PetesPockets -

My mention of possible post mint damage are the horizontal lines on the cheek and breast at 11 and 12 o'clock in my close up. Agree with consensus the circular ridges caused by a tool polished die.

The first close-up photo of the reverse is interesting, but currently uninterpretable.
