This 5 Rubles coin was issued by the USSR in 1990 as a copper‑nickel commemorative celebrating the Matenadaran Institute of Ancient Manuscripts in Yerevan, Armenia. The obverse shows the Soviet state emblem with hammer and sickle, denomination “5 РУБЛЕЙ,” country name “СССР,” and date 1990 below. The reverse depicts the monumental façade and stairway of the Matenadaran, a famous repository for medieval Armenian manuscripts, with Armenian script, a stylized scroll, and the inscription “Ереван 1959,” marking the year the current building was inaugurated. Part of the late Soviet architectural‑heritage commemorative series, the coin weighs about 19.8 g, measures 35 mm, and has a plain edge.
