How to Spot a Fake Coin

When growing your coin collection, it’s imperative to work with someone that is reputable and reliable. But no matter where you’re procuring your coins, especially if a coin is particularly valuable or rare, you must be on the lookout for counterfeits. Spotting fake coins may be tough, but it’s doable.

There are three common types of counterfeit coins and three key ways to identify these different fakes. With a bit of know-how, you’ll be protected from unknowingly wasting money on fakes.

Three Types of Counterfeit Coins

Cast Coins: Casting fake coins is the cheapest and most common way to counterfeit. By using an authentic coin’s casted mold, a counterfeiter pours a mixture of metal in it to create a fake. These molds have often been taken or copied from a facility to produce a coin with a startling likeness to the original. A cast coin is preferable to a struck coin because it’s a quick, easy way to replicate coins. The mixture of liquid metal poured into the cast often results in a coin that is nearly indistinguishable from the real coin you’re seeking to add to your collection.

Struck Coins: Counterfeiting struck gold and silver coins is a more complicated process than casting fake coins. Essentially, false struck coins are created similar to the method used by mint manufacturers. The counterfeit is created by placing a flat, round metal disk, called a planchet, between two coin dies. These coin dies are pressed together by a hydraulic press, molding the planchet into a replica coin.

Doctored Coins: A doctored coin is created by altering a regular coin until it looks either rare or antique. A common coin, cast by a mint, is distressed with slight engravings or etchings, so it appears more valuable than it is. Alternatively, counterfeiters will “split” coins. Splitting is a counterfeit style where two coins, one inexpensive and one seemingly rare, are merged to create one that appears to be valuable.

How to Identify a Counterfeit Coin

Dimensions: Each coin produced by the India Mint has specific dimensions that verify the authenticity of a coin. These dimensions include the coin’s metallic content, weight, diameter, thickness, and year of minting. You can check some of the measurements of the coins through this technique.

Visual: Examine the coin in question with the assistance of a magnifying glass. Look for small inconsistencies such as mismatching surface texture, text spacing, seams, markings, and edges. Then, compare these visuals to an authentic coin- you can either compare to the one you already own or find a high-quality image online. If you notice differences between these two coins, you may very well have a counterfeit coin on your hands.

Magnetic: Both silver and gold are non-magnetic metals. For this reason, neither a fine gold nor a fine silver coin should have any magnetic reactivity to a magnet. This is a very simple test- grab a magnet, preferably a stronger one, and place it near your precious metal coin. If the coin is attracted to the magnet, you know you have a fake. Iron and steel are very magnetic metals and are often used in the production of counterfeit coins.

While it’s possible you’ll stumble across a counterfeit coin, and now you’re equipped with the knowledge to spot them and not waste your money. For future purchases, it’s crucial to purchase from a reputable company like Mintage World, to protect and continue to grow your collection.
