I suggest that your circulated Lincoln cent is simply a nicely worn example of a common 'grease filled strike' - a striking issue whereby debris clog the die and prevents certain design elements from fully being struck.
The photos provided show no evidence of a lamination -
nickelsearcher: Great job answering this question correctly. The only thing I would have added would have been: "The grease fills the narrow part of the devices, leaving them looking wider but shorter." You get an 'A'.
