How to avoid fake coins


01 November 2022
A modern plague threatens collectors and investors with an increasing number of fake coins being sold via the internet. Sebastian Wieschowski provides an in-depth guide to avoiding these counterfeit coins

The problem of counterfeit coins is not a new phenomenon. In 2017, the Royal Mint estimated that 2.5% (around £44m) of the old £1 coin was counterfeit. In recent years, many coin dealers and precious metal sellers have noticed an upsurge in the number of counterfeit items being offered.

In the field of modern bullion coins, counterfeit ounces of gold and silver are often sold on auction platforms such as eBay or offered to dealers for resale.

When you look at some of the more questionable coin websites, you can easily see: Anything that has the potential to make money on the European and American coin market is counterfeited. Even high-mintage circulation coins from the German ‘Third Reich’, which are sold for 50 cents apiece at coin fairs, are imitated in bulk quantities at Asian factories.

Counterfeiters also use gold bars. To deter forgery, many ingot manufacturers weld their bars into hard plastic cases. This elaborately produced shell should serve as an authenticity feature. But counterfeiters have become so good at forging even this casing that it is no longer a dependable means of determining the authenticity of a bar.

‘The fakes are becoming more sophisticated, says Waldemar Meyer, store manager at Germany’s largest precious metals dealer ‘pro aurum’ in Berlin and head of the non-profit ‘German Precious Metal Society’ initiative. Recently, fraudsters have even begun to sell fake gold bars with a counterfeit-proof of purchase.

As more and more internet auction sites offer investment coins and bullion, the risk of buying counterfeits has grown. While inexperienced investors may easily be fooled, reputable traders can spot a sham.

This may sound banal, but you can't go wrong following this advice from mints and consumer advocates: to avoid fake gold coins and bars, buys exclusively from reputable sources. This is always the safest option.

Unlike individual or unknown traders selling on online auction sites, merchants obtain gold bars exclusively from recognised producers who themselves have quality control to LBMA standards as well as check the ingots and coins they buy from the secondary market using various testing techniques for authenticity. This guarantees their customers that they can buy them with confidence.

Many traders consider the problem of counterfeit gold bars to be overblown by the media. This is so because according to big European refineries, very few gold bars being melted contained tungsten and are fake. However, this does not take into consideration the fact that many dealers test their gold bars before sending them to a refinery. Therefore, it does not say anything about the number of fake bars in circulation. This, in fact, simply prove that buying exclusively from reputable sources reduces the risk of buying a counterfeit bar.
