Yeah, I thought it was kinda crude too. I noticed that it was less than 18K in the end. Can't make coins out of that unless it gets refined further. I'm surprised they didn't do that there, seeing as how they already had it melted.Seems like a slapdash way of cleaning it at the end. Surely they would be filing lumps out of it?
how do they remove the alloy metals from all that jewelry to make pure gold ? interesting video
