I know this is not a Lincoln cent,
however I needed a nice example of an authentic clipped penny with the "Blakesley Effect" opposite the clipped area of the coin. (All my older Lincolns are encapsulated and it is hard to photograph up close.)
This Blakesley effect is caused by the raising of the opposite side of the planchet from the clipped area creating a raised rim where it is weakly struck.
The presence of the Blakesley effect is assurance of authenticity, however the absence of it doesn't always imply that it is not authentic due to the random nature of how clipped planchet errors happen.
Also Note the smooth metal flow at the edges of the clipped areas.
