The Uthman Qur'an

The Uthman Qur'an (also referred to as Tashkent Qur'an and Osman's Koran) is a manuscripted copy of the Qur'an, which was (until the discovery of the Sana'a manuscripts) considered to be the oldest in the world. It is said to still have a stain of blood from the assassination of the 3rd Caliph, Uthman ibn Affan.
