1. Weighing: the true gold ingot has a high density, and its weight is consistent with its volume. There is a big difference between the weight and the real gold. It may be a fake. Weighing is a preliminary method to judge the authenticity of gold ingots, and weight is not the only criterion.
2, look at the color: the real gold ingot is golden yellow with high gloss. The color is gray or black, which may be fake. Color may be affected by many factors, such as oxidation, dust, etc.
3, test hardness: gold is soft, lightly scratch the surface with nails or copper keys, real gold will leave traces. No trace or shallow trace may be false, and hardness test may cause damage to Jin Yuanbao.
4. Seizure: The interface and tether of the real gold ingot are handled exquisitely. The interface is rough and the tether is abnormal, which may be fake. The interface and tether can also be replaced later.
