How to Tell if a Silver Coin is Real

how to spot fake silver

One thing I hate is scammers out to con you into shelling out hard-earned money for counterfeit silver coins. Unfortunately, this happens way too often, and so I’ve put this blog together to go through some surefire ways to determine whether coins and bullion are real silver…or just not.

To (hopefully) spare you from the pain of discovering fake silver for yourself, I went ahead and bought a bunch of “silver” coins from the notorious 

Let’s see how much useless metal I actually have. 

Tools of the trade

To authenticate your silver coins, you’re going to need a few tools:

  • A neodymium magnet
  • A digital scale, 
  • A digital calliper set or a standard ruler 
  • A reference guide such as the Krause book or US red book. 

You can buy all of these on Amazon. With these in hand, you are ready to examine your coin for authenticity. Let’s break down the process into three basic tests: the magnet test, the weight test, and the dimensions test.

How to Spot Fake Silver Coins

1. The Magnet Test

Silver and gold are not magnetic. Thus, if your coin sticks to a neodymium magnet, it’s not genuine. For instance, when I tested a fake American Silver Eagle Bull Round, it clung to the magnet— a clear sign that it was a counterfeit.

While the magnet test tells us that a coin is not silver, it doesn’t tell us whether a coin is actually silver. For that, let’s jump over to the next test. 

2. The Weight Test

Precise digital scales are instrumental in determining a coin’s authenticity. Using one of the reference guides above, you can easily see how much a particular coin is supposed to weigh if real.

Always cross-check the weight of your coin with a reliable reference. For instance, a Morgan Silver dollar should weigh 26.73 grams. Note that a real coin that’s had some of the metal worn away over the years might show up to be slightly underweight, and that’s OK. But a significant deviation from this weight is a red flag.


Before we can be completely satisfied that a coin is silver, it needs to pass all of our tests. 

Which brings us to:

3. The Dimensions Test

The final step in our process is the dimensions test. By using a digital calliper set, you can measure the diameter and thickness of your coin. If your coin’s measurements differ significantly from the standard specifications for that coin, it’s probably a fake.

To illustrate, a real Krugerrand should have a diameter of 32.7mm and a thickness of 2.85mm. If your coin is significantly larger or smaller than these dimensions, it’s likely not genuine.

Please note: a coin must pass all three tests to be considered genuine. Failure in just one test deems the coin a counterfeit.

Something to remember

The above tests primarily confirm the authenticity of the silver in the coin. Some counterfeiters may use actual silver to produce fake numismatic coins. That’s why it’s crucial to pay close attention to the design, lettering, and overall quality when assessing numismatic coins.

Where to buy real silver coins

If you want to skip the testing and just make purchases safe in the knowledge that what you’re buying is the real deal, look no further than Apmex. You don’t get the reputation Apmex has without an unwavering commitment to quality – there are no magnetic American Silver Eagles anywhere near this site. 

I buy a lot of my bullion coins from Apmex. And, if I smell an opportunity, I’ll turn to Whatnot and see what I can get at one of their online auctions. You can get $15 of Whatnot credit using my link.

Both options are great, and certainly better than!
