It’s not unusual for coin collectors to stumble across counterfeits, which is why it’s crucial to recognize the differences between reproductions and genuine articles. If you’re in the market for silver or gold coins or want to confirm the authenticity of something you’ve found, use these tips.

How to Tell If a Coin Is Authentic

1. Test Their Magnetism

Silver and gold are not magnetic materials. If you position a magnet adjacent to the coin in question, it won’t budge if it’s authentic. But if it moves even a little bit, then it’s likely an artificial product that contains steel or iron in its composition. Bear in mind, though, that just because it doesn’t attract a magnet doesn’t mean it’s not fake.

2. Check the Relief

The relief refers to the height of the coin’s image. Counterfeiters usually can’t replicate the relief height exactly, so the image is either set too low or too high. If you were to stack a fake on an authentic coin, it would likely topple.

3. Inspect the Markings

Use a magnifying glass to inspect the coin closely. If possible, compare it to an authentic one for verification. Check details such as the denomination, mint year, font, and artwork. Run your hand over all sides and feel for inconsistencies like unusual changes in texture. While a counterfeiter can create nearly identical replicas, they can’t easily copy those minuscule markings that distinguish real from fake.

4. Assess the Edges

Silver and gold coin edges are distinctive and so intricate that they aren’t easily replicated. Some are ridged in areas, while others alternate between smooth and textured to create more complex edges. If you know the pattern of a genuine coin’s edge design, use that as a comparison point for the one you’re checking. Look for signs of counterfeit design, like uneven spots or gaps of the wrong size.
