Spectroscopic techniques in the investigation of extraordinary medieval Polish coins: Revealing the presence of hidden cores

Nukleonika
Cross denars, frequently found in Polish hoards, were traditionally thought to be Ag coins with some Cu content. This study investigates the possibility of a hidden Cu core beneath the Ag or Ag–Cu surface of these coins. It raises questions about whether
