For the first time in domestic and foreign historical science, a systematic and generalized study of historiographical nature was carried out, in which the scientific achievements of the problems of money circulation of Dnieper Ukraine from the end of the XVIII century were analyzed before the reforms in the Russian Empire in the 1860s of the imperial, Soviet periods and during the times of independent Ukraine.
The historiography of the issues of reform in the field of monetary affairs, which in the early nineteenth century was conducted by M. Speransky. There is a positive attitude of researchers of all historiographical stages and state systems to the measures of reform proposed by M. Speransky, but the opinions of researchers differ on the effectiveness of the implementation of the planned steps of reform. Experts are emphasize the priority of objective factors (the war with Napoleon) and subjective factors (actually implemented the secondary provisions of the reform, etc.), which led to the fact that the reform did not have the expected effect. The dissertation notes that the weakness of historiography is the lack of fundamental research on the impact of M. Speransky's reform and its implementation in the Ukrainian provinces, counties, cities and villages.
Regarding the history of counterfeiting, there is a lack of systematic and generalized works in the scientific work, which would relate to the entire period defined by the chronological framework of the dissertation research. Some works cover the issue of counterfeiting banknotes in the context of legal research on the history of the state and law, the activities of public authorities (one of the tasks of which was to combat counterfeiters). It is also emphasized that existing publications often do not differ in in-depth critical analysis of available information, which is often expressed in the production and dissemination of existing non-historical myths and so on. At the same time, there is fundamental scientific research on certain events that took place in the field of counterfeiting, such as the spread of counterfeit banknotes by the French during the Napoleonic Wars.
In matters of the functioning of paper banknotes, it is emphasized that the main scientific material was accumulated during the imperial times by such researchers and contemporary specialists and statesmen in the field of finance as I. Kaufman, E. Lamansky, V. Goldman, P. Niikolsky and others. There is no single vision of the periodization of the introduction and operation of paper banknotes, but most researchers agree with the idea of accumulation from the time of banknotes (in the XVIII century) to the late 1830s, when the fundamental reform of the paper money system began in the Russian Empire in general, and in the Ukrainian lands in particular. It is emphasized that in Soviet times, the history of paper money and the history of money circulation in general during the Russian Empire did not interest researchers, although in the last decades of the Soviet Union, such works have appeared. Ukrainian researchers have been using the works of paper money since the time of independence, dealing with the issue of paper banknotes, and the issue of the functioning of paper banknotes specifically in the Ukrainian provinces is mentioned in the context of other studies.
Regarding the historiography of E. Kankrin's reform and its influence on the continued existence of the monetary system of the Russian Empire, it is noted that active coverage of the issue began only twenty years after his death, that is in the 1860s, because researchers of the monetary system at that time tried to analyze the causes of new crisis phenomena, at this time financial science was actively developing in the empire, in particular in the free economic zones of the Ukrainian provinces. Scientific achievements at this time highlighted some of the shortcomings of the reform, although in general positively highlighted its results. In Soviet times, due to the negative ideological attitude to E. Kankrin, there were no works devoted purely to this reform. After the collapse of the Soviet Union, E. Kankrin's reform is considered by Russian researchers to be somewhat idealized, from the point of view of exclusively state interests, and so on. It is emphasized that Ukrainian researchers emphasize the ambiguity of E. Kankrin's reform activities through the prism of its impact on the population of the Ukrainian provinces.
Among the promising topics of further research are issues of money circulation in the Ukrainian provinces in general, individual provinces and counties, the history of the mints in Ukraine, the implementation of reforms M. Speransky and E. Kankrin, which would not be based on fundamental imperial research, but on the materials of local Ukrainian archives.
