Top 10 Rare Pennies of the Twentieth Century
1. 1943 Copper Lincoln Cent – rare pennies of the twentieth century
The 1943 copper cent is the most famous modern penny error. Minted mostly in steel that year due to wartime needs, a few copper planchets were mistakenly struck and remain extremely scarce.
Identification tips:
- Color: true copper tone, not silver-gray like 1943 steel cents.
- Weight: copper cents weigh about 3.11 grams; steel cents are lighter and often plated.
- Authentication: requires X-ray fluorescence or professional grading to confirm metal content.
2. 1909-S VDB Lincoln Cent – rare pennies of the twentieth century
The first year of the Lincoln cent produced a small number of coins with the designer V.D.B. initials on the reverse. The San Francisco 1909-S VDB is scarce and a classic key date.
Identification tips:
- Look for the large VDB initials on the lower reverse rim.
- Even worn specimens retain value; condition matters for price.
3. 1914-D Lincoln Cent – rare pennies of the twentieth century
The 1914-D Lincoln cent from Denver had a low mintage and is a key date for many collections. High-grade examples are especially difficult to find.
Identification tips:
- Confirm the small ‘D’ mintmark under the date.
- Compare devices and rim thickness to known genuine examples.
4. 1922 Plain (No D) Lincoln Cent – rare pennies of the twentieth century
Most 1922 cents from Denver show a weak ‘D’ or none at all because of a soft strike. Fully struck ‘no D’ pieces are collected as an error variety and can command premiums.
Identification tips:
- Examine the reverse around the mintmark area for remnants of a punched mark.
- Authentication by an experienced grader helps because die issues can mimic absence.
5. 1931-S Lincoln Cent – rare pennies of the twentieth century
The 1931-S is a key date Lincoln cent with low mintage. It is well known among collectors and often on lists of coins to search for in circulation and old holdings.
Identification tips:
- Locate the small ‘S’ mintmark beneath the date.
- Look for strong details on Lincoln’s bust to improve value potential.
6. 1955 Doubled Die Obverse Lincoln Cent – rare pennies of the twentieth century
The 1955 doubled die obverse displays very strong doubling of the date and the wording on the obverse. This error is visually dramatic and one of the most famous midcentury rarities.
Identification tips:
- Check the date and the words ‘IN GOD WE TRUST’ for clear doubling.
- Photograph the coin at high resolution to compare with reference images.
7. 1944 Steel Lincoln Cent – rare pennies of the twentieth century
After the 1943 steel issue, most 1944 cents were struck on bronze. A few 1944 steel error cents are known and are prized by specialists.
Identification tips:
- Steel cents are magnetic; perform a magnet test carefully to avoid damage.
- Confirm metal content with an expert to rule out plating or alterations.
8. 1969-S Doubled Die Obverse Proof Lincoln Cent – rare pennies of the twentieth century
The 1969-S doubled die obverse proof is a specialized variety found mostly in proof sets. Its rarity and striking doubling make it a target for proof coin collectors.
Identification tips:
- Look for doubling on the date and motto on the obverse under magnification.
- Proof surfaces will show mirror-like fields and frosted devices.
9. 1972 Doubled Die Obverse Lincoln Cent – rare pennies of the twentieth century
Another modern doubled die, the 1972 doubled die obverse is recognizable by doubling of the legend and date. Many examples were discovered and submitted for grading, but certified high-grade pieces remain valuable.
Identification tips:
- Compare the doubling to verified examples from reputable references.
- Beware of machine-made doubling or post-mint damage that can look similar.
10. 1999 Wide AM Lincoln Cent – rare pennies of the twentieth century
Late twentieth-century varieties such as the 1999 Wide AM (reverse legend spacing) are lesser-known but sought after by variety collectors. While not as dramatic as older keys, these can be valuable in high grade.
Identification tips:
- Compare the spacing between letters ‘A’ and ‘M’ on the reverse.
- A good reference guide or certified example helps distinguish close varieties.
Some of the most valuable twentieth-century pennies were discovered in ordinary pockets, old coin rolls, or family collections. Errors and low-mintage dates can hide in plain sight for decades.
Practical steps for verifying rare pennies of the twentieth century
Always start with basic checks: weight, color, and mintmark location. Use a magnifier and compare to high-quality reference images before paying for grading.
When in doubt, consult a reputable grading service or an experienced numismatist. For high-value finds, professional authentication and certification will protect your investment.
