Ne tylko Kurozwęcki! O niektórych problemach identyfikacji fałszerstw monet Królestwa Polskiego z końca XV wieku.

ENThe first part focuses on the types of forgery and the problems related to their recognition. Not all forgeries are primitively made, and those considered to be such may be the product of mints with very good technical equipment. The situation on the money market was sketched, reflecting on the number of monetary counterfeits in circulation, since there are individual pieces in the hoards. Most of the counterfeit coins were produced during the reign of Jan Olbracht (John Albert), but they are known not from hoards but from collections without a record of the find. Many counterfeits were made in workshops with a very high level of technology and therefore these coins are considered genuine.The second part presents analyzes of three cases, selected in such a way as to solve a problem that requires the use of a different method in each case. Several coins with a visible layer of copper were selected for the first test. The test consisted in determining whether it is the copper from which the coin core or the sediment was made. In the second case, the execution of the coin (both the planchet and the dies) was analyzed. Then, the characteristics of the analyzed and reference coins were compared. In the last case, the experience from the analysis of the coin making technique was used, supplemented with epigraphic analysis. It seems that the method of analysis of the execution technique has great development potential and the obtained results are very promising. [From the publication]
