The only coin featuring the Lincoln Memorial is the cent from 1959 to today, so I don't know exactly what your set consists of. A complete set from 1959 - 2008 would only bring $5 or $6 if all the coins were picked from circulation.
The next time a memorial was brought on the agenda was in 1934, when an admirer of Jefferson, President Franklin Roosevelt, suggested a memorial of Thomas Jefferson to build on the site. This time the congress did accept the project and gave it 3 million dollars.
