Things You'll Need
Instructions
Find an example of an authentic coin on helpful resource websites such as "Silver Coins." This website provides pictures of authentic silver coins alongside counterfeit coins to help learn the difference.
Check the weight. Different coins have different approximate weights that may vary by very small amounts. For instance, according to "Silver Coin," a 1796 Draped Bust dollar typically weighs about 27 grams. If you found a coin that weighed a great deal more or less, you could safely assume it is a fake.
Look at the edges. Some coins are minted with smooth edges; others have a border known as reeding. Reeding appears as a border of lines at regular intravals around the coin, forming a series of bars. If the coin you are buying has reeding when it should not or does not when it should, it is a fake.
Compare the lettering and numbering. Often fake coins have letters or number that are larger, smaller or in a different style than the authentic coin.
Examine the images on the coin. Counterfeiters often come close to replicating the images on the original coins but get some of the details wrong. Look at details such as the hairstyle or clothing of the figure on the coin.
Examine the small details of the coin. Usually coins have small decorations around the pictures. For instance, the 1796 Draped Bust dollar has stars around the bust on the head side. The original of that coin has eight stars on the left of the bust and seven on the right. A different amount of stars means it is fake.
Compare the price of the coin with current market value. If someone is offering you a silver coin for $75 that normally sells for $200, be suspicious. Using good common sense is your best weapon against acquiring a fake coin.
