When it comes to identifying real gold coins, most coin dealers will tell you that the secret lies in the density of gold coins. In comparison to other metals, gold is far denser. This fact is to the advantage of gold coin collectors as creating counterfeit gold coins extremely difficult given that the weight of the coins has to be just the right volume. Below are a few important tips that can help you properly identify real gold coins. Interestingly enough, the method used here dates all the way back to BC and it works with both pure gold and gold alloy coins: 1. Find out if the coin is supposed to be 22K or 24K gold. Pure gold or 24K gold is softer than 22K gold and is more prone to damage. This is why a majority of pure gold coins are alloyed with the use of a different metal, such as copper and silver, in order to make them harder. Some coins such as the American Buffalo and Canadian Maple Leaf gold coin do not undergo the alloying process. There are many coin catalogues that you can pick up in book stores or peruse online to help you find out what the composition of a specific gold coin is. Coin dealers can also help you with the process. 2. Pick up a graduated measuring container and fill it up with water. Be sure to take note of the exact volume of water. Drop the coin in the container and make sure that no water splashes out in the process. Read the volume of the water. Next, proceed to subtract the original volume of the water from the volume displayed after dropping the coin in the container. For instance, if the original volume of water in the container was 30.0 cubic centimetres, and the volume after adding the coin is 35.0 cubic centimetres, the volume of the coin is 35.0 cc minus 30.0 cc or 5.0 cc. 3. Calculate the coin’s density. Density can be computed by dividing the weight of the coin by its volume in cubic centimetres. For instance, if the coin weighs 30.0 grams and the coin’s volume is 5.0 cc, then its density its 6.0 g/cc. A coin that is pure gold has a density of around 19.3 g/cc while 22K gold coins have densities of about 18.5 g/cc. In order to identify real gold coins, find out first whether the coin is supposed to be 22K or 24K gold. Then, proceed to measure its volume and density. Feel free to repeat the measurements and calculation until you get an accurate reading. In order to be certain, it is recommended that you seek the services of reputable coin dealers. coin dealers
