Counterfeit Detection: Take a Look at Whizzed Coins

The art of numismatics involves more than just collecting coins; it also requires an understanding of how to spot counterfeits and altered coins. Among the various techniques used to deceive collectors, whizzing is one of the most common methods of coin alteration. A whizzed coin might look dazzling at first glance, but its artificial shine conceals the fact that it has been tampered with. For collectors and dealers alike, recognizing a whizzed coin is essential to avoiding costly mistakes.

What Are Whizzed Coins?

Whizzing is a mechanical process used to make a coin appear uncirculated or in better condition than it actually is. This is done by using high-speed tools such as rotary brushes, drills, or abrasive materials to polish the coin’s surface. The goal is to give the coin a bright, lustrous appearance that mimics the natural cartwheel luster of a freshly struck coin.

While a whizzed coin may initially seem appealing to an untrained eye, closer examination often reveals its artificial nature. This type of alteration is considered deceptive because it enhances the coin’s appearance without adding any real value, and it can significantly mislead collectors about the coin’s true grade and authenticity.

How to Spot a Whizzed Coin

Distinguishing a whizzed coin from one with genuine luster requires a keen eye and attention to detail. Here are some key indicators to look for:

1. Unnatural Surface Texture
   The surface of a whizzed coin often appears unnaturally smooth or has a rippled texture. The tool used in whizzing can leave behind fine scratches or grooves that disrupt the coin’s original design details.
2. Loss of Design Detail
   Whizzing removes a thin layer of the coin’s metal, which can blur or soften the fine details in the design. Elements like lettering, hairlines, and stars may look less sharp than they should.
3. Altered Luster
   Genuine luster results from the way light reflects off the flow lines of a coin created during the minting process. In contrast, a whizzed coin reflects light differently, creating a flashy yet unnatural shine. The cartwheel effect seen on uncirculated coins is usually absent.
4. Raised Areas of Inconsistency
   High points on the coin, such as the cheeks of a portrait or the eagle’s feathers, may appear overly polished. These areas often show clear signs of tampering, with a different texture or color compared to the rest of the coin.

The Impact on Value

Whizzed coins lose much of their value because the alteration makes them less desirable to collectors. Even if the coin is a rare date or type, the damage caused by whizzing significantly diminishes its appeal. Many grading companies, such as PCGS and NGC, label whizzed coins as “altered surfaces” or “cleaned,” which can drastically affect their marketability.

Protecting Yourself from Whizzed Coins

To avoid purchasing a whizzed coin, always buy from reputable dealers and consider having coins graded by a professional third-party service. Examine coins carefully under magnification and in proper lighting to spot inconsistencies. Familiarizing yourself with genuine luster and surface textures will also improve your ability to identify altered coins.

Conclusion

Whizzed coins are a deceptive alteration that can trick even experienced collectors. Understanding how to detect these tampered coins is crucial for preserving the integrity of your collection and making informed purchases. With vigilance, knowledge, and a commitment to quality, collectors can steer clear of whizzed coins and focus on acquiring genuine numismatic treasures.
