At PBN, we assist issuing authorities with efficient and profitable disposal of their currency that is no longer needed for circulation.

We handle large stocks of currency, including circulated coins in large quantities for destruction (smelting), uncirculated coins and banknotes in large quantities for the numismatic market, and specialized accumulations of currency.

We also advise issuing authorities on conversion to polymer banknotes, on banknote security features, and on coin and banknote numismatic programs.
