Use these values to verify an authentic Gold Kangaroo 1/10 oz. All tests can be performed with a digital scale, calipers, and the EON ping tester.
Use a 0.01g digital scale. Calibrate first with a known object (a €2 coin = 8.50g).
Use plastic calipers (not steel — avoid scratching). Or use the camera tool with a bank card as reference (ISO 7810: 85.60mm × 53.98mm).
Balance the coin on your fingertip and tap the edge with a pencil or plastic pen. Use the Ping Tester to analyse the ring.
