I don't mean to sound disrespectful,  but.....wouldn't these coins be result of a mint weak strike error? I certainly do not have the experience that I'm sure you have but I thought/think the above applies.  Perhaps the pictures that I furnished do not show what no rother strike to reverse is apparent. Thanks again for taking the time to review and replying.

I have two pennies 1972D and 1964D Lincoln Memorial.  The obverse is relatively clear on each (although 72 wording IGWT is not visible with naked eye but can be seen using microscope) the reverse side of each coin is similar.  The 64 however only shows 6 pilares whereas the 72 shows more building/pilares  what type of error is this and do coins have value .  Sorry for being so long winded, I am just very new to coin collecting and roll hunting  Thanks!,

I understand the zinc rot.....is that what you're referring to in wording States? 

As area notes, i am RELLY NEW to coin roll hunting/error coins.  Came across this 1992D Lincoln Penny and noted reverse of coin.  Is this machine Doubling?
