Well just like I advise digging the zinc pennies for gold I'll also say the same for pull tabs. This 4th July weekend I was working under a tree at a high school and had just hit a half dozen tokens in a three foot area and then got a sold hit at vdi 19 with a bounce to 20 on the back swing. For me that's a usual nickel or the good old pull tab. About three inches down I pull out this nice 14K ring, so yes I dig a lot of junk but I also find the gold. Photo of the ring on a mirror so you can see top and bottom (it's only one ring).
