No way, never even try to do it. My best find ever is the knowledge and insight into history while doing the research that leads to good sites. That and learning about those RIO's I've found. (Rusty Iron Objects) I was honestly ignorant about the difference between Ox shoe and horse shoes at one time.
The gold I've piled up is sitting in a couple shoeboxes collecting dust. Rings, bracelets, etc.. Same for the silver. Once you've dug it, stock it and forget it. There's more to be dug. I've posted before some of my favorite finds included rusty opened knives, screws, nails, bullets and broken glass in the city playgrounds. Being an old man with lots of scars I know I've kept a few from happening, that's good enough for me and as good as it gets.
