Among numismatic artifacts, one can find not only genuine specimens but also historical counterfeits. An example of such an object is a counterfeit 1913 three-kopek coin, preserved from an old collection. This coin was most likely produced by casting, as evidenced by its characteristic porosity.

Three types of counterfeit 5-ruble gold coins, produced in different workshops, were selected for examination. Each counterfeit is compared with an authentic coin from the same year of issue. A total of six coins were prepared for the analysis: three fakes and three originals.
