Vanilla Coke and Nordic without liquid in them

[tognaco]

Hello everyone, I am Antonio from Seville, Spain. I am not really a can collector, but I have some cans I'd like to get some information about and I thought you could help me. Two of them are Vanilla Coca-Cola zero sugar cans without any liquid in them. I don't know how it can have happened, because the cans have never been opened and any of them have any kind of hole in them. Both of them are in a very good condition. Besides, I have two more cans without any liquid in them, but in this case they are Nordic Tonic cans. Without any hole either. I don't know if they have any kind of value, can you please tell me anything on that regard? Thank you very much in advance.
I enclose two pictures of the cans.
