How do you validate a coin?

Coin authenticity verification involves meticulous examination of various physical attributes. One crucial aspect is the color, which is inherent to every coin and serves as a unique identifier. Each metal alloy used in minting exhibits a distinct hue, making color analysis a fundamental step in verification.

Brightness is another vital characteristic that can be discerned during the verification process. This attribute is acquired during the minting process and, similar to color, is specific to the alloy composition. Variations in brightness can indicate tampering or the use of non-standard materials.

Smoothness is a key factor in assessing the authenticity of a coin. The unengraved portions of a genuine coin should be flawlessly smooth, even, and devoid of any porosity. Imperfections in these areas can be indicative of counterfeiting.

Wear and tear patterns also play a significant role in verifying the authenticity of coins. Naturally occurring wear patterns are often distinct and consistent with the coin's age and use. In contrast, artificially induced wear can appear irregular and inconsistent.
