Depicts the coat of arms of Estonia (1925–1940), the country name (Republic of Estonia) above, the date below.

The coat of arms of Estonia showcases a shield with three lions depicted in a passant-gardant position, flanked by oak branches. Each lion symbolizes different aspects of Estonian history, representing ancient freedom struggles, uprisings in Harjumaa in 1343, and the fight for independence between 1918 and 1920. The wreath of oak leaves surrounding the coat of arms signifies Estonia's enduring resilience and commitment to freedom.

Originating from the arms of Danish king Valdemar II in 1219, these lions were initially part of the greater coat of arms of Tallinn and the surrounding fiefdoms. Despite Denmark's sale of its Estonian dominion in 1346, the lions retained their prominence in Tallinn's coat of arms and later became central to various Estonian coats of arms, including those of the Duchy of Estonia and the Governorate of Estonia. Finally, upon Estonia's independence, the Riigikogu officially adopted the national coat of arms on June 19, 1925, cementing its role as a symbol of national identity.

Depicts Toompea Castle, the denomination below.

Toompea Castle, situated atop Toompea hill in the heart of Tallinn, holds a rich history dating back to at least the 9th century. Legend has it that the entire hill was meticulously crafted by Linda, who painstakingly assembled it stone by stone with her own hands. This myth lends Tallinn the traditional nickname of Lyndanisse, meaning "The nipple of Linda" in Estonian. However, the more factual narrative reveals that ancient settlers in Estonia utilized the naturally fortified hill as a stronghold, eventually transforming it into a bustling commercial center. It likely stood as one of Tallinn's earliest inhabited areas.

Following Estonia's Declaration of Independence in 1918, a parliamentary building was constructed on the former site of the Teutonic Order's convent. Completed in 1922, the structure was envisioned by architects Eugen Habermann and Herbert Johanson. While its exterior maintains a traditional aesthetic, the interior showcases Expressionist design, making it the world's sole Expressionist parliament building.
