This bill proposes amendments to the Convention on Cultural Property Implementation Act, primarily to facilitate the lawful trade and collecting of numismatic materials . It introduces a specific definition for "numismatic material," encompassing items such as coins, tokens, paper money, and medals, to ensure clarity in its application. The legislation modifies import restrictions by requiring satisfactory evidence for numismatic materials, demonstrating they were lawfully acquired, are of a known type, and are not the direct product of illicit excavations. This evidence must include declarations under oath from the importer, attesting to the material's lawful acquisition and export, its documented type, and its origin not being from illicit excavations. Furthermore, the bill restricts customs officers from demanding additional documentation beyond these specified declarations, unless there is probable cause to suspect the provided evidence is false or fraudulent.
