Change currency of products without affecting the value

Question

How would you change the currency of a product's price within a storeview, without affecting the actual value? I would like to do this at once to all products within a store view as I have more than 5000+ products.

E.g: USD400 -> EUR400, not EUR286.77(value conversion)

Answer 1

If you want to change the currency symbol.

Navigate to

Admin > System > Configuration > General > Currency Setup

Change Base Currency to  => Euro
Change Default Display Currency to => Euro

Or one more Ugly way to do this. (Not Recommented)

Admin > System > Manage Currency > Manage Symbol

Change the Symbol for US Doller to EUR
