Coin is dedicated to the 100th anniversary of discoveries made by an expedition headed by American professor-archaeologist Rafael Pampelli at an excavation site near the village of Annau, a few kilometers to the west from Ashgabat. It should be recalled that scientists discovered traces of highly advanced civilization and the remaining of white wheat grains cultivated by ancient grain growers 5,000 years ago. Findings made by Pampelli’s expedition proved that inhabitants of ancient settlements situated near modern Ashgabat were the first people in the history of mankind to grow wheat and barley and bake bread from white wheat flour.
