In the vast realm of numismatics, the study and collection of coins, there exists a multitude of captivating mysteries and curiosities. One such enigma that has fascinated coin enthusiasts and magnet aficionados alike is the magnetic properties of US coins. While most coins are not typically magnetic, certain factors and compositions can influence their behavior in the presence of a magnet. Join us on this captivating journey as we delve into the magnetic allure of US coins, exploring which coins are irresistibly drawn to the pull of a magnet and uncovering the fascinating stories behind them

What US Coins will stick to a Magnet?

The Magnetic Personality of Steel Cents

Imagine the surprise of stumbling upon a coin that adheres effortlessly to a magnet. One such intriguing numismatic anomaly is the steel cent, a rare and unusual coin with an intriguing magnetic personality. During World War II, the United States faced a copper shortage, prompting the government to explore alternative materials for coinage. In 1943, the US Mint produced Lincoln cents using zinc-coated steel, resulting in a unique magnetism. These steel cents, often referred to as “war pennies,” possess magnetic qualities due to the steel core. When subjected to a magnet, they exhibit an alluring attraction that sets them apart from other US coins.

The steel cent’s magnetic allure has led to various theories and legends surrounding them. Some believe that these magnetic coins were intentionally made to aid in wartime efforts, ensuring that they were not easily lost or misplaced by soldiers. Others speculate that their magnetic properties were a result of accidental contamination during the minting process. Regardless of the true origins, steel cents remain a fascinating chapter in the magnetic saga of US coins.

The Astonishing Attraction of 1944-1945 Silver Nickels

Continuing our magnetic odyssey, we encounter another remarkable coin that defies expectations—the silver nickel. Amidst the tumult of World War II, the United States faced a critical shortage of nickel, prompting the US Mint to temporarily alter the composition of five-cent coins. From 1942 to 1945, Jefferson nickels were minted using an alloy known as the “wartime silver” composition, which consisted of 35% silver, 56% copper, and 9% manganese. This alloy not only reduced the amount of precious nickel used but also introduced a surprising magnetic allure.

The magnetic properties of these silver nickels are due to the presence of the ferromagnetic metal manganese. When a magnet approaches a 1944-1945 silver nickel, the coin experiences an extraordinary attraction, clinging to the magnet’s pull. This peculiar behavior distinguishes these wartime nickels from their non-magnetic counterparts and adds a layer of intrigue to their historical significance.

The Magnetic Mystery of Coins with Nickel Core and Copper-Nickel Clad Layers

Venturing deeper into the realm of magnetic US coins, we encounter yet another captivating anomaly—the coins with a nickel core and copper-nickel clad layers. Introduced in 1965, this composition was implemented for the dime, quarter, and half-dollar denominations. These coins, commonly referred to as “clad coins,” feature a magnetic core surrounded by non-magnetic outer layers.

The magnetic core of these coins is primarily composed of a mixture of nickel and copper, while the outer layers consist of a copper-nickel alloy. This combination creates an intriguing scenario where the core exhibits magnetic properties, while the clad layers do not. When subjected to a magnet, these coins respond with a moderate attraction, showcasing their unique magnetism.

The Unyielding Non-Magnetism of Copper Coins

In the realm of magnetic US coins, one category stands out for its unwavering resistance to the magnetic pull—a group of coins crafted from copper. Copper, an elemental metal widely used in coinage, does not possess inherent magnetic properties. Therefore, US coins predominantly composed of copper, such as the pre-1982 Lincoln cents and the copper-nickel Jefferson nickels minted since 1982, do not exhibit any magnetic response when brought near a magnet.

The non-magnetic nature of copper coins is deeply rooted in the material properties of the metal itself. Copper possesses diamagnetic properties, meaning it generates an opposing magnetic field when subjected to an external magnetic force. Consequently, when a magnet is brought near a copper coin, the diamagnetic effect counteracts the magnet’s pull, resulting in no discernible attraction between the two. This inherent resistance to magnetism adds a layer of stability and consistency to the vast array of US coins, offering a distinct contrast to their magnetically alluring counterparts.

The Magnetic Anomaly of Silver Coins

In the magnetic tapestry of US coins, silver occupies a unique position. While the majority of silver coins do not exhibit significant magnetic attraction, there are instances where silver coins can display a slight magnetic response due to specific factors. Silver, as an element, is not inherently magnetic, similar to copper. However, the presence of certain impurities or alloys can introduce magnetic properties to silver coins.

One such example is the 1943 silver war nickel we discussed earlier. The silver content in these nickels, combined with the presence of manganese, imparts a degree of magnetism to the coin. However, it’s essential to note that this magnetism is relatively weak and not as pronounced as the magnetic coins we explored previously. Additionally, some rare silver coins may contain minute traces of magnetic metals as impurities, resulting in a subtle attraction to magnets.

It is crucial to understand that the magnetic response of silver coins is an exception rather than the rule. The majority of silver coins, such as the pre-1965 90% silver dimes, quarters, and half-dollars, do not exhibit any magnetic properties due to their pure silver composition. The allure of silver coins lies in their historical significance, precious metal content, and numismatic value rather than their magnetic behavior.


The magnetic properties of US coins offer a captivating glimpse into the intricate world of numismatics. From the steel cents of World War II to the magnetic anomalies of silver nickels and clad coins, these magnetic marvels defy expectations and ignite the curiosity of coin enthusiasts. While copper coins stand firmly resistant to magnets, silver coins occasionally exhibit slight magnetic responses due to impurities or specific alloys. Each coin possesses its own tale, weaving a fascinating narrative that adds depth and intrigue to the diverse tapestry of US coinage.
