Uncashable Foreign Coins & Banknotes

Hi there,

I was wandering if any of your fundraising departments had any accumulated stocks of demonetised banknotes or coins lying around. By the term demonetised I mean the countries or types of notes that banks or bureaux will not accept. I know that many charities have their own personal ways of disposing of current currency, however, what happens to the remainders?

I would appreciate any help.

Many thanks
