The large coat of arms of the Republic of Latvia, with the year 2005 inscribed below, is placed in the centre. The inscriptions LATVIJAS and REPUBLIKA, each arranged in a semicircle, are above and beneath the central motif, respectively.

The Latvian national coat of arms was designed by the Latvian artist Rihards Zariņš. It combines symbols of Latvian national statehood, as well as symbols of its ancient historical districts:

- The three golden stars above the field represent three historical provinces: Vidzeme (Swedish Livonia), Latgale (Polish Livonia) and Kurzeme-Zemgale (Duchy of Courland and Semigalia).
- The golden sun in the field represents the sun of freedom. Sun symbol was used as a symbol of distinction and national identity by the Imperial Russian Army's Latvian Riflemen units during World War I. During the war, the sun was fashioned with 17 rays that symbolized the 17 Latvian inhabited districts.
- The bottom part of escutcheon is divided into two fieds where the red lion of Courland represents Kurzeme and Zemgale while the silver griffin of Polish Livionia represents Vidzeme and Latgale. The red lion and silver griffin are also used as Supporters.
- Base of the coat of arms is decorated with the branches of an oak tree, Quercus robur, which is one of Latvian national symbols

The rooster on the spire of St. Peter's church in Riga is featured in the upper part of the coin. The numeral 1, with the inscription LATS in a semicircle on the right, is arranged in the lower part.

St. Peter's Church (Latvian: Svētā Pētera Evaņģēliski luteriskā baznīca) is a Lutheran church in Riga, the capital of Latvia, dedicated to Saint Peter. First mention of the St. Peter's Church is in records dating to 1209. A sphere and rooster were set atop the steeple 10 May 1690.

Artillery fire destroyed the church on 29 June 1941. Conservation and restoration began 1954 with research by architect Pēteris Saulītis. The work was carried out from 1967 to 1983 under the direction of Saulītis and architect Gunārs Zirnis. A rooster – a precise reproduction of the previous rooster and the seventh rooster in all – was placed atop the steeple 21 August 1970.
