The paper work presents different aspects about the dies damages appeared at the metal holed coin striking process. In the paper beginning part, some particular introductive considerations about the holed metal coins manufactured with cracked dies error are presented; there are presented some examples. Then the simplified blank and the obverse and reverse dies 3D model are introduced, followed by the assembled model which consist in the obverse and reverse negative dies having the coin blank inside them. For these models, the finite element analysis is computed and achieved for different initial inputs. In the last part of the paper work, the analysis results and main conclusions on these are presented.
