At PBN, we help the 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 bank notes in large quantities for the numismatic market, and specialized accumulations of currency.

We also advise the issuing authorities on conversion to polymer bank notes, on bank note security features, and on coin and bank note numismatic programmes.
