That is a very good question, on which I don’t have the answer (yet)!
I’ve just checked with the guys that minted the coins. They should know 😉
I’ll let you know as soon as I have more information on this one!
The 2 euro Germany is not out yet, except very limited quantities at private banks. These are more expensive today.
Your best shot is to wait for April when they will be officially released by the Bundesbank 😉
