The Ultimate Guide to Spotting Rare Proof Lincoln Cent Errors from 1936-1942

Introduction: The Devil is in the Details

Most people overlook the tiny details that can transform a common item into a rarity worth thousands. When it comes to Proof Lincoln cents from 1936-1942, these small nuances can mean the difference between a nice collectible and a truly exceptional investment piece. As an error coin hunter, I’ve learned that the shallow end of the pool often hides the deepest treasures.

Historical Significance of 1936-1942 Proof Lincoln Cents

The Proof Lincoln cent series from 1936-1942 represents a fascinating period in American numismatics. These were the first regular-issue proof cents produced since 1916, marking the return of proof coinage after a 20-year hiatus. The United States Mint resumed proof production in 1936, creating coins specifically for collectors rather than just for archival purposes.

During this seven-year period, the Mint experimented with different finishes and techniques. The early pieces (1936-1942) were struck with a brilliant finish, though some 1936 cents were also produced with a distinctive satin finish that is now considered “almost unobtanium” by serious collectors. The metal composition remained consistent at 95% copper and 5% tin and zinc throughout this era.

Identifying Key Markers: What to Look For

Die Cracks: The Fingerprint of Aging Dies

Die cracks are raised lines that appear on coins when the die itself develops fractures during the striking process. On Proof Lincoln cents from this era, die cracks can appear in several locations:

• Through the date or mint mark
• Across Lincoln’s portrait
• Along the rim or between design elements

Die cracks are particularly valuable when they’re dramatic or when they create what collectors call “cud” errors – areas where a piece of the die has broken off completely, leaving a raised blob of metal on the coin. These errors become more common as dies age and are used extensively.

Double Dies: When the Image Appears Twice

Double die errors occur when the die itself is struck more than once during its creation, causing a slight shift between impressions. This results in a doubled image on the finished coin. For the 1936-1942 Proof Lincoln cents, several notable varieties exist:

“If you do varieties, there is a class 2 DDO for ’39 and a class 2 DDR for ’38. Just sayin’.” – Forum contributor

DDO stands for Doubled Die Obverse, while DDR means Doubled Die Reverse. The 1939 Class 2 DDO shows clear doubling on the obverse (heads side), particularly noticeable in the date and lettering. The 1938 Class 2 DDR exhibits doubling on the reverse (tails side), often visible in the wheat stalks and motto.

Mint Mark Variations: The Subtle Differences

While all Proof Lincoln cents from 1936-1942 were produced at the Philadelphia Mint (which didn’t use mint marks during this period), variations in the design elements themselves can occur. Pay special attention to the size and position of the letters in “LIBERTY” and “IN GOD WE TRUST.” Even slight variations in spacing or letter size can indicate different die varieties that may command premium prices.

The Mysterious “Below the 8” Anomaly

One forum contributor asked, “What is that below the 8?” This cryptic question likely refers to a die anomaly or die break that appears near the number 8 on certain date varieties. Such anomalies are exactly what error hunters look for – they’re unique to specific die states and can make a coin significantly more valuable to specialists.

Specific Errors to Look For in 1936-1942 Proof Lincoln Cents

1936: The Gateway Year

The 1936 proof cent comes in two finishes: brilliant and satin. The satin finish is exceptionally rare and can sell for many times the price of the brilliant finish. Look for a softer, more matte appearance on the satin examples.

Key errors to watch for include die cracks through the date and various stages of die deterioration that create unique patterns on the coin’s surface.

1937: The Blazing Red Specimen

As one collector noted about their 1937 specimen: “Absolutely blazing RED!, especially the ’37’.” This observation highlights the importance of color in these coins. Full Red (RD) examples are the most desirable, followed by Red-Brown (RB), then Brown (BN).

Die anomalies in 1937 often appear as fine die cracks around Lincoln’s profile or through the wheat stalks on the reverse.

1938: The DDR Year

The 1938 proof cent is notable for the Class 2 Doubled Die Reverse mentioned earlier. This error shows distinct doubling in the wheat ear details and the motto “E PLURIBUS UNUM.” Using a 10x loupe, examine the reverse carefully for any signs of doubling.

1939: The DDO Variety

The 1939 proof cent features the Class 2 Doubled Die Obverse. This error is most visible in the date, where the numerals may appear slightly doubled, and in the word “LIBERTY.” The doubling is often subtle but becomes apparent under magnification.

1940-1942: The Later Years

These years continued to produce interesting die varieties and errors. As dies wore out during the war years, die cracks became more prevalent. The 1942 cents may show more pronounced die deterioration due to increased production demands as America entered World War II.

Authentication and Grading: PCGS and CAC

Many serious collectors, including the original poster, aim to assemble sets of PCGS (Professional Coin Grading Service) graded coins with CAC (Certified Acceptance Corporation) stickers. CAC approval indicates that a coin is especially nice for its grade.

For Proof Lincoln cents from 1936-1942, the goal is often to find examples in Proof 66 Red or higher. As one commenter wisely noted: “getting gem red CAC proof Lincoln cents from that era is not necessarily the ‘shallow end of the pool’.”

Investment Potential and Market Considerations

The original collector’s goal of assembling an all-matching set of PCGS and CAC’d Proof 66 Red cents is ambitious but potentially rewarding. As coins in this set increase in grade and rarity, their values can increase exponentially.

The 1936 satin finish, if you can find one, represents one of the greatest challenges and potential rewards in this series. Similarly, the doubled die varieties from 1938 and 1939 can command significant premiums over regular proof cents.

Conclusion: The Thrill of the Hunt

As the original poster concluded: “Thanks everyone for your positive comments. I know it will be a battle and I’m looking forward to the challenge!” This sentiment captures the essence of error coin hunting and specialized collecting.

Whether you’re just starting your journey with Proof Lincoln cents or you’re a seasoned collector looking to upgrade your set, remember that the most valuable finds often come from knowing what to look for. Those tiny details – the die cracks, the doubled images, the subtle variations – are what separate the common from the exceptional.

Happy hunting, and may your collection be filled with blazing red gems and fascinating errors that tell the story of these remarkable coins!
