typical images associated with the regions they represent. All commemorative coins are in circulation on a par with the standard ones and are a good source of increased interest among collectors. In pursuit of learning from the experience of countries such as the United States, Austria, Canada, etc., starting 2011 the Central Bank of Armenia has been issuing silver bullion coins of the series "Noah's Ark". These coins represent 7 weight categories from 1/4 oz to 5 kg. The purpose of the project is to provide opportunities for households to invest their extra money in silver coins. A well-chosen theme of the issue as well as excellent quality made it possible to sell over million pieces of these coins in just a year. The concept of reflecting most important cultural and historical aspects on banknotes and coins is most clearly and vividly realized in the issuance of collector coins. From 1994 to date, more than 170 high-quality collector coins have been issued. These coins are dedicated to the Armenian state, great Armenian generals, history of Armenian currency, formation of the Armed Forces of Armenia. Many coins have also been issued to commemorate birth anniversaries of renowned people of science, literature, culture, and sports. Much attention is given to Christian values: these are ancient temples and churches, and spiritual values of the past. The diversity of animal and plant life is reflected in the issues that deal with rare and unique species of fauna and flora of Armenia. Planned and systematic work to improve the quality of the banknotes and coins in Armenia could not be left unappreciated. Many issues have won awards at the most prestigious international numismatic forums. This book, dedicated to the 20th anniversary of Armenian dram, contains the most comprehensive list of issues of notes and coins of Armenia. We hope that this work will be interesting and useful not only for numismatists, but also for those who takes interest in Armenia with its rich culture and history.
