what type of error is this 1968-S cent

rainy day and kids went to bed, left me with a moment of free time to start organizing my office. Found the remnants of a large collection I purchased earlier this year, mostly junk from Littleton, was getting ready to dump a group of rolls of Unc misc lincolns into circulation and this came out of the tube. Perhaps I should look closer at these rolls from Littleton before I spend them.
Is this a struck through grease, die alignment strike or something else. Weight is right on

Check the weight. At first glance it looks like a thin planchet.
I concur.
weight is correct, so must be from grease,
What is the weight?

i agree.
Tom (The Captain) that without knowing
the weight, a rolled thin planchet was a
good probability, over a 'filled dies' error.
Since it's the correct weight, I say it's
a weak strike, and not a filled die.
Interesting - I would have agreed with

I agree (as usual) with Fred and Tom. Filled dies would have resulted in a less uniform pattern of weakness across more of the design. Instead the weakness on the reverse correlates exactly with the deepest parts of the obverse design, meaning the metal was not under enough pressure to fill those areas of the dies.
The two most common causes for this are a thin planchet (which would be underweight) or a weak strike. Since the weight is on spec, that precludes the former possibility.
