Precious Coin Tester

Comparing results between specific gravity test, a Sigma Metalytics PMV we own and this Ping testing AP it’s been spot on as are the above two that we depend on to make sure no fakes exist in our stack. For fast accurate detection on the fly we have come to depend on the Coin Tester AP. We’ve subscribed to it and are willing to accept the results without question. It’s well worth the cost and piece of mind. So if your on the fence about using this AP and or subscribing go for it. It’ll save you a lot of grief and pay for itself.
