The Standard of the President of Russia is a squared Russian tricolour defaced with the coat of arms of Russia, the banner of the Russian Armed Forces also has the coat of arms centered on the obverse side. Some state awards of Russia are also designed based on the coat of arms, including the State Prize. Russian ruble coins depict the coat of arms on the obverse side since 2016.

Eventually, St George became the patron saint of Moscow (and, by extension, of Russia). After the assumption of the title of Tsar by Ivan IV, the two coats are found combined, with the eagle bearing an
