A profile portrait of Đorđe Petrović (Karađorđe) partially covered by a profile portrait of King Petar I Karađorđević, both facing to the right, surrounded by the inscription "Petar I. Karađorđe". Engravers initials below.

Peter I (Serbian: Петар; 1844–1921) reigned as the last King of Serbia (1903–1918) and as the first King of the Serbs, Croats and Slovenes (1918–1921). Since he was the king of Serbia during a period of great Serbian military success, he was remembered by Serbian people as King Peter the Liberator, and also known as Old King.

Đorđe Petrović (Serbian: Ђорђе Петровић), better known by the sobriquet Black George, or Karađorđe (Serbian: Карађорђе) (1768–1817), was a Serbian revolutionary leader who fought for his country's independence from the Ottoman Empire during the First Serbian Uprising of 1804–1813. Karađorđe is considered the founder of the Karađorđević dynasty, which ruled Serbia in several intervals during the 19th and 20th centuries.

Denomination below Greater coat of arms of Kingdom of Serbia. Date above.

The coat of arms consists of two main heraldic symbols which represent the national identity of the Serbian people across the centuries, the crowned Serbian eagle (a white double-headed eagle adopted from the Nemanjić dynasty) and the Serbian cross.

The Serbian cross, a national symbol of Serbia, based on the tetragrammic cross emblem/flag of the Byzantine Palaiologos dynasty. It is composed of a cross symbol with four stylized letters "S" (С) in Cyrillic on each of its corners, heraldically referred-to as "firesteels", which historically originate as the Greek letters beta (β–Β).
