Clinker,
Great post! I've actually been putting together a Lincoln type set for a couple months now, ever since I ordered my Lincoln dollars. I"m going to do a coin type set, a paper money type set, and a world coin and paper money type set, all in three or four separate shadow boxes to display on my wall. I'm actually having them all graded by PCGS, just so they will match, but also to make them easier to mount in the boxes.
From what I see you're just missing the 1991 Mt. Rushmore commemorative clad half, silver dollar and $5 gold coins and the South Dakota state quarter.
Also, you could consider the following, if you wanted to invest a substantial amount of money into it. All of the following portray Lincoln:
1861 $10 US Demand note
1862 $10 US Demand note
1863 $10 US Demand note
1863 $20 Interest Bearing note
1869 $100 US note
1869 & 1875 Fractional .50c note
1875 $100 US note
1880 $100 US note
1882 $500 Gold Certificate
1899 $1 Black Eagle Silver Certificate
1922 $500 Gold Certificate
those are just some other things to consider

very nice post Clinker!
