Not quite sure what type of lamination error this is. The area in the date is not a "bubble" as it appears, but is solid.
If the 1983 (mid 82 and later) cents are very thin copper plated zinc cores, then how can the bubble in the date be solid ?
I agrer.. Clearly a Linear Plating Bubble. It's not another digit. Copper bubbles are not like soap bubbles. They are a bit tougher than that!
blisters can be hollow or solid, hollow blisters are formed by gases trapped under plating, solid by corrosion being pushed up... http://www.error-ref.com/blisteredplating/
Sorry dollar but they are all correct above. The entire surface shows a problem with plating on this coin.
They are all right, of course, in saying it is a plating bubble. But, for the sake of argument, let us suppose it is a minor die chip or break. With the surface of the rest of the coin there is no way you could prove it without some kind of expensive metallurgic x-ray exam, and if you did prove it, it would raise the value of the coin from 1 cent to maybe 5 or 10 cents. In other words, spend it.
