20. Chao cipher: Its not technically unsolved, but no one knows why is was in author J.F. Byrnes autobiography.

23.
23. Blitz Ciphers: These were discovered during WWII in a bombed cellar in East London. They depict 50 calligraphic symbols possibly 18th century Freemason ciphers.
24.
24. Bellaso Ciphers: Bellaso, a 16th century Italian cryptologist, is responsible for many techniques used today and many of his challenge ciphers have yet to be solved.
25.
25. Bacon Cipher: Sir Francis Bacon created these ciphers in his literary works. There has been speculation that he was responsible for Shakespear's works, but there has been no conclusion made.
