Armenia's 1st issue of postage stamps. Type 2.
Due to increased rates, postage stamps were revalued. Russian kopeck-denominated stamps of the 1909–1917 issue, perforated and imperforate, were revalued to a new denomination—60 kopecks—by applying an overprint with single hand-held rubber stamps of two types: "k 60 k" (without dots) and "k. 60 k." (with dots).
Kopeck-denominated stamps were chosen for revaluation because, after the rate increases, they had long not been used at their face value, and therefore survived in sufficient quantities. In addition, the light color of the stamps ensured a clear and sharp overprint of the new denomination.
The revaluation was carried out centrally at the Erivan post-and-telegraph office. One of the two stamps remained at the office until September 16, 1924, when it, together with other stamps, was transferred under a formal act to the organization of the Authorized Representative for Philately and Paper Money in the USSR.
A significant number of provisionals is associated with the Civil War of 1918–1922. During this time, stable central authority was absent in most of the country, many regions became independent, and the devastation of war led to significant inflation. Frequent rate changes and the inability to supply the postal network with stamps of the required denominations led to periodic revaluations of existing stocks in accordance with instructions of the People's Commissariat of Posts and Telegraphs of the RSFSR, which did not provide for any overprints. However, locally, some postal institutions still applied overprints to the revalued stamps being sold, or simply added the new value by hand. All of these stamps are characterized by extremely simple overprinting techniques.
