The 1940s were a fascinating time for U.S. coinage, marked by material changes, minting errors, and rare design variations. While many coins from this decade remain common, a few stand out due to their extreme rarity and high value.
Collectors are willing to pay enormous sums for these rare finds, with some coins selling for hundreds of thousands of dollars.
Below are five of the most valuable U.S. coins from the 1940s and the reasons behind their worth.
1. 1943-D Bronze Lincoln Cent – $840,000
During World War II, the U.S. Mint switched from copper to zinc-coated steel for pennies to conserve copper for the war effort.
However, a few leftover bronze planchets from 1942 were accidentally used in 1943, resulting in an ultra-rare bronze penny.
The rarest of them all is the 1943-D Bronze Lincoln Cent, with only one known specimen from the Denver Mint. This unique coin sold for an incredible $840,000 in 2010, making it one of the most valuable pennies ever found.
Why It’s Valuable:
- The only known 1943-D penny struck in bronze.
- Produced during a year when pennies were supposed to be made of steel.
- Considered a one-of-a-kind error coin.
2. 1943-S Bronze Lincoln Cent – $504,000
Similar to the Denver version, the 1943-S Bronze Lincoln Cent was mistakenly struck on a bronze planchet instead of steel.
Unlike the single known Denver coin, a few examples from the San Francisco Mint exist, though they are still extremely rare.
One of these coins sold for $504,000 at auction, proving how much collectors are willing to pay for these historical mistakes.
Why It’s Valuable:
- One of the few 1943 pennies struck in bronze.
- Rare and highly sought after due to its unique minting error.
- Only a handful of these coins are known to exist.
3. 1944-S Steel Lincoln Cent – $373,750
In 1944, the U.S. Mint returned to using copper for pennies, but a few leftover steel planchets from 1943 were mistakenly used.
This resulted in the 1944-S Steel Lincoln Cent, an exceptionally rare coin with only two known specimens.
One of these coins sold for $373,750 at auction in 2008, making it one of the most valuable wartime minting errors.
Why It’s Valuable:
- A 1944 penny mistakenly struck on steel instead of copper.
- Only two known examples, making it one of the rarest Lincoln cents.
- A fascinating error that showcases the challenges of wartime coin production.
4. 1940-D Jefferson Nickel – $21,737.50
The 1940-D Jefferson Nickel is not inherently rare, but high-quality versions featuring Full Steps on the Monticello design command premium prices.
“Full Steps” refers to sharply defined steps on the building, which are difficult to find due to weak strikes and wear from circulation.
A 1940-D Jefferson Nickel graded MS-68 Full Steps sold for $21,737.50 at auction, making it one of the most valuable nickels from the decade.
Why It’s Valuable:
- Rare in Mint State (MS-68) with Full Steps.
- Exceptional strike quality makes it highly collectible.
- One of the finest known examples of a 1940 Jefferson Nickel.
5. 1940 Walking Liberty Half Dollar – $45,000
The 1940 Walking Liberty Half Dollar, designed by Adolph A. Weinman, is widely regarded as one of the most beautiful U.S. coins ever produced. While millions were minted, finding one in pristine condition is extremely rare.
A 1940 Walking Liberty Half Dollar graded MS-68 has an estimated value of $45,000, with some high-grade examples selling for $29,375 at auction.
Why It’s Valuable:
- Highly sought after in top grades (MS-68).
- Considered one of the most beautifully designed U.S. coins.
- Rare in uncirculated condition due to heavy circulation use.
