Yeah, it's funny. I just unwrapped a 10 oz silver prospector bar from Silvertowne yesterday, the first of this kind for me. I know that the 1 oz bars have been faked, but haven't seen anything about the 10 oz. My only problem with the piece is that the prospector and donkey in the circle has a sandblast finish to it, whereas all the pictures I see on the internet have a shiny finish. The engraving is high quality, but now I need to chase down more information about this type of bar.
