While coins are typically more expensive, they are also more easily sold, since they are legal tender and guaranteed by the government.#2 The purity of a gold coin is measured in karats. The higher the karat number, the purer your gold. 24 karat gold is the purest gold available, but it is softer and less dense than 22 karat gold, which is used in some popular coins.#3 The purity of a coin can be determined by its metal weight. The higher the percentage of precious metal, the more valuable the coin.
