I have some of each Lincoln issue. WL's 1967SMS is a prime example of how nice modern Lincolns can be. Here is one of my modern Lincoln Memorial cents. There are nice ones too be found All the images at this link are courtesy of @robec who does amazing work. I still have many upgrades too send his way Robec's Images: Gi Joe.
As I recall it was around 1958 at a Pennsylvania estate auction with my father that I saw a cent in a dresser drawer. I had a moral decision to make...let it go and possibly be spent or save it. I couldn't let it be circulated, so I snicked it. Well, I sent it to the plastic factory last month...PCGS MS63BN.
This is most collectors reaction when they find out most of my Lincoln cent registry sets have Penny in the title
