"I got all his personal info, full name, address, phone number (house and mobile), bank account number, etc."??
You can post that all over the internet and have his Identity stolen... that would get back at him.
*I don't endorse or recommend you doing that, just an idea*
I don't understand... Why don't you just send a picture and Email COCA-COLA themselves? They will be able to tell you. Maybe not the price, but atleast the year and more information about it.
