The coins look different, I have never seen that exact type that I remember. They are probably brass or coated. I'm going to guess were made to be a token or reproduction, They lack the detail of an actual coin. Fantasy coin, Maybe? I'm almost positive they aren't from 1912.
What's it worth? Not much. to be honest!
The bars? I can only guess, since I don't have much experience in world bars, or .........Or whatever they are?
All I can say is....Hope you didn't get stuck buying this stuff for a lot of money! No offense meant! And it might just be the pictures too!
