> And what are your thoughts on it? Pretty expensive, with tax and shipping it was around $2k or so. I don’t know if I buy enough bullion to justify the cost, but there’s a lot of fake coins and bars coming from China and elsewhere that are pretty convincing. The counterfeiters are becoming very sophisticated, and eventually it’s going to cause issues with the precious metals collectors. I don’t want to be that guy that thinks he has gold/silver bullion but instead has fakes… Edit: sorry I guess I should answer the question lol. It works as advertised, at least I think it does. It measures the thickness of the coins/bars and then tests the “resistive” or “conductivity” of the metal. You also need a scale to measure the weight, but with all of that info you can tell if you have legit bullion or not. The coins have to be a minimum size, 1/10 of an ounce I think. I have a small bar, 1 gram, that I wasn’t able to ascertain if it was real or not because it was too small and in a package, but it works well with everything 1/10th of an ounce and larger. For bars that are too large to be measured by the device it has separate probes that you can buy for extra $$ to test those as well. If you’re a serious stacker it’s probably worth the $$ for the peace of mind. That and be sure to get your precious metals from a reputable source.
