You are buying a genuine California placer gold nugget that I laminated in a ten mil pouch for durability that you can put in your wallet or attach to your detecting equipment for easy access. This is a perfect size test nugget for either PI or VLF detectors. The nuggets vary from 4 to 5 grains each, or .26 gram to .33 gram each. (You will not receive the one that is in the photo.) The nuggets vary in appearance and shape. You will not have a choice.
The card also has a conversion table for easy computations. The back side also has my shameless advertising – LOL!
