The 500 Ruble note, introduced in 1912, is by far the physically largest banknote printed by the Russian Empire and one of the largest banknotes seen in the world. The note bears the portrait of Czar Peter I, also known as "Peter the Great." This was the largest denomination printed by the State Bank. The note also has an impressive watermark of Czar Peter I, a former ruler. This feature of a former ruler's watermark has previously only been seen in the 25 Ruble and 100 Ruble notes.
