A set of 50 State Lincoln coins

wheelman

I found a set of 50 state Lincoln cents. Has anyone seen these or know any thing about them. They're dated 1979.

Each coin has a outline of each state to the right of Lincoln's face and above the date.

Here's a couple photos.

Someone just added the outline- a post-mint alteration

These are pretty common except that 1974, '5 and '6 are more typical. There
are at least three different sets of dies which struck these. There were also
several other dies used in '76 for the bicentennial.
