Coin restoration from old Molten account.

Hello,

im writing this to verify one question. Is it possible to still regain coins bought on old account played during Molten-days?
I had an account registred on and old a email of mine on wich i bought around 40 coins at the time i was playing there. It was on Neltharion realm on Cataclysm expanions, on character named Byros (horde BE Hunter).
Later after rebranding your server to Warmane, i've created new account (beacause it required @gmail registration) wich i barely played.
Now i've returned to your server and i've met one of my friends from Neltharion days who told me you did refound coins bought on Molten.
If it is still possible please tell me wich information you will require from me, (for example credit card details).

Thank you for help,
Igor a.k.a Byros
