While looking at a collection of Lincoln pennies, a peculiar flaw in
one caught my eye. I have a 1974-D Lincoln Memorial penny in XF
condition, but the top of Lincoln's head is slightly flat. The
appearance shows more spacing between the word "WE" and the top of
Lincoln's head. I looked through the other 1974-D pennies I had and
couldn't find another like it. I was wondering if anyone else had
come across a penny like this, and whether this can be classified as
a minting error?
