Классификация русских удельных монет

A. A. A. Ilyin's book "Classification of Russian appanage coins" is devoted to the extremely complex but fascinating topic of appanage coinage, which was characterized by extreme diversity in various to varying degrees independent territories of the future Russian Empire. The book consists of four sections: - Coins of Chervonnaya Rus - Coins of the Grand Duchy of Lithuania - Coins of the Grand Duchy of Ryazan - Coins of the Grand Duchy of Suzdal-Nizhegorodsky The book was published in Leningrad in the pre-war year 1940 and represents the most important stage in solving the difficult problem of classifying the money issued and circulated in the appanage principalities of its time.
