Depicts a stylized map of Budapest, featuring the word "BUDA" on the Buda side and "PEST" on the Pest side. Positioned at the bottom right of the map is the coat of arms of the capital city, beneath which the designer's initials (GG) are displayed. On the left edge, in the center, the inscription "125 YEARS" is presented in two lines.

The capital's Gothic coat of arms, predominantly red in color, is divided by a silver or white wavy ribbon, symbolizing the Danube River. The upper field of the shield features a one-towered, single-gated, gold (yellow) structure representing Pest, while the lower field depicts a three-towered, double-gated, gold-colored castle representing Buda and Óbuda. Both castle gates are open against a sky-blue background. Positioned on the right side of the shield is a gold-colored lion, while on the left side rests a gold-colored griffin (a lion-bodied eagle). The Hungarian Holy Crown is placed atop the shield.

Depicts the Chain Bridge at its center, with the Buda Castle depicted in the background. Positioned on the right side, at the top, is the denomination, followed by the inscription "FORINT" below it. In the lower third, consecutive rows of inscriptions including "Hungarian Republic," the year of issue and mint mark, along with the engraver's initials, are visible.

The Széchenyi Chain Bridge, known as Széchenyi lánchíd in Hungarian, spans the River Danube, connecting Buda and Pest, the two sides of Budapest, Hungary's capital city. Designed by English engineer William Tierney Clark and constructed by Scottish engineer Adam Clark, it holds the distinction of being Hungary's first permanent bridge over the Danube. Completed in 1849, the bridge is anchored on the Pest side to Széchenyi Square and on the Buda side to Adam Clark Square. Named after István Széchenyi, a key supporter of its construction, it is commonly referred to as the "Chain Bridge" due to its chain-link design. Renowned as a marvel of modern engineering upon its completion, the bridge's decorations are crafted from cast iron.
