Error Cent?

Just face value. As you start to pour over thousands of cents you'll begin to see trends. With the Zincoln cents, there are many things going on with the devices that have doubling appearances. As noted above by our colleagues, Die Deterioration and zinc rot at select spots are about your specimen.

Common issues with Zincolns of the '80s and early '90s.

Zinc rot (hydrozincite) at various spots on the coin, but most notably where there are hard corners (vertices) where the copper plate is stretched so thin that it splits exposing the zinc to he elements.
Over use of die sets leading to circumferential splitting of the plating and raised relief towards the rim and ghost like images adjacent to devices, especially the date (as is with your specimen)
Uneven toning of surfaces - especially those left in the cup holders of cars to get corroded by soda, coffee, anything that spills.

But keep asking questions here - lots of folks willing to help out if they can. Good luck on your hunts!

Awesome info rackster Thank you!
