This paper looks at the issue of digitalization in coin business, as well as criteria for assessing coins for integrity using a case study of the Nikolai II silver roubles. Catalogization has always been a pre-requisite when dealing with coins. The criteria for assessing coins were changing throughout the entire historic period while they were being collected. One can distinguish such assessment criteria as integrity, wear, rarity and condition. The object of research includes Nikolai II silver coins that were mass produced by the Saint Petersburg and Brussels mints with participation of the Mining Institute’s graduates, silver and gold m nzmeisters. Certain features related to the fire assay tests of coins are considered. However, the use of data collected with the help of modern instruments, as well as the use of specialized software packages to assess a metallic item appear to offer more details and consistency for creating a real digital platform in the field of numismatics. E-catalogues with new data on the wear factor may serve as the first step towards coin systematization within a digital platform. The study of silver coins was carried out using hi-tech equipment of several research centres encompassed by the Saint Petersburg Mining University. This paper is devoted to the 250th anniversary of the Mining University, the first engineering university of Russia, and to its most distinguished graduates, who became famous coin experts.
