The email contact that I sent you might be able to help you out on this. This is the first time that I have seen a Chattanooga Coca-Cola bar like that. I also sent him a private message on Facebook and I sent him the link to your thread in order for him to take a look at it. Sorry that I was not much help on this. I am still learning about Coca-Cola silver art bars and I apologize for not replying to you any sooner than now. I hope that this helps.
