My colleagues in Germany somehow changed the home currency from US$ to Euro as they were exploring the system for their potential use. Now I have over 600 potentials from the US with data in Euros. 

What I could find in the help files regarding changing it back is not at all encouraging. Is there anyway to change the home currency back to US$ and / or mass update the currency value for the potentials? 

There MUST be something

Thank you
