Coin collecting is a hobby filled with fascinating discoveries, especially when it comes to mint errors. A mint error occurs when a coin is made incorrectly during production, leading to unique and rare items that collectors treasure. One of the most interesting errors involves the Kennedy Half Dollar, a famous U.S. coin, which was struck on a magnetic planchet. This rare occurrence makes this particular coin highly special. Let’s take a closer look at this unique mint error and why it’s such a valuable piece in the world of numismatics.
What is a Magnetic Planchet?
A planchet is the blank metal disk used by the U.S. Mint to create coins. In this case, the Kennedy Half Dollar was struck on a magnetic planchet, which is an unusual type of metal disk. Magnetic planchets are typically used for washers or other industrial purposes, not for coins. When the planchet was struck, it was expanded to the size of a regular Kennedy Half Dollar. However, this magnetic planchet lacked the smooth, reflective surface that is usually seen on proof coins. This is what makes the error so interesting!
The Story Behind the Coin
This unique coin, a 1968-S Kennedy Half Dollar, was struck with an off-metal planchet error. The planchet used was magnetic, which is highly unusual for coin production. Fred Weinberg, a known expert in mint errors, owned this coin for decades before selling it in 2024. He said, “As far as I know, this is the only known U.S. Proof mint error struck on a magnetic planchet.” This statement further adds to the coin’s rarity and value.
Certification and Features
This rare Kennedy Half Dollar has been authenticated and certified by PCGS (Professional Coin Grading Service) as Proof 62. It doesn’t have the usual polished finish of a regular proof coin, and the cameo portrait of President Kennedy is not visible on the obverse (front). Instead, the coin has the look and color of a mint-state U.S. coin that was struck on a smaller magnetic washer. Despite the unusual surface and appearance, the coin is still a valuable and intriguing piece in the world of coin collecting.
