Depicts the coat of arms of the Kingdom of Serbia (1882–1918) in a circle of pearls.

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).

Denomination in the center surrounded by legend "Kingdom of Serbia" and date.

Mintmark (if any) below the digital "20".
