Is Your 1943-D/D RPM-3 Lincoln Cent Real? How to Spot a Fake

Historical Significance

The 1943-D Lincoln cent represents a fascinating chapter in American numismatic history. Struck during World War II when copper was needed for the war effort, these coins were made from zinc-coated steel instead of the traditional bronze composition. This wartime emergency issue makes them immediately recognizable and historically significant to collectors.

Authentication Guide: Key Diagnostic Points

With counterfeits flooding the market, knowing the specific diagnostic points for this item is critical. The 1943-D/D RPM-3 (Repunched Mint Mark) variety is particularly vulnerable to misidentification and counterfeiting due to its subtle characteristics.

Weight Verification

Authentic 1943 steel cents should weigh approximately 2.7 grams. This is significantly lighter than the 3.11 grams of bronze cents from other years. Always use a precise digital scale when authenticating these coins. Any deviation beyond 0.1 grams should raise immediate concerns about authenticity or potential alterations.

Magnetic Properties Test

Due to their steel composition, genuine 1943 cents are strongly magnetic. This is one of the easiest initial tests for authentication. If your coin is not attracted to a magnet, it is definitely not a steel cent from 1943. Be aware that some counterfeits are made from copper and artificially aged to appear authentic.

Die Markers and RPM Characteristics

The RPM-3 variety shows a repunched mint mark where the “D” mint mark appears doubled or shows evidence of being punched twice in slightly different positions. According to expert analysis, what was initially identified as RPM-3 may actually be RPM-009, a different variety entirely. The key diagnostic feature is the specific positioning and appearance of the doubling.

Examine the mint mark under magnification (10x loupe minimum). Look for these specific characteristics:

• The direction and angle of the doubling
• The relative position of the secondary mint mark
• The strength and clarity of the repunching

Common Fakes and Alterations

Several types of counterfeits exist in the marketplace:

1. Copper-plated steel cents from 1943 altered to appear as rare varieties
2. 1948-D cents with the “8” altered to look like a “3”
3. 1943 Philadelphia cents with added mint marks
4. Authentic 1943-D cents with artificially enhanced RPM characteristics

Testing Methods

For serious collectors, these additional tests can help verify authenticity:

Professional authentication services like ANACS, PCGS, or NGC provide the most reliable verification. Their experts can examine die characteristics, strike quality, and other subtle features that distinguish genuine varieties from counterfeits or misidentified coins.

Advanced collectors might also consider:

• XRF (X-ray fluorescence) analysis to verify metal composition
• Microscopic examination of die wear patterns
• Comparison with known genuine specimens from reputable sources

Value Guide

The value of a 1943-D/D RPM-3 cent depends significantly on its grade and the specific variety. According to forum discussions, the RPM-009 variety (which may have been misidentified as RPM-3) is considered a “non-cherrypicker’s variety” and would typically command a lower premium than more dramatic varieties.

For a MS66 example, values can range from $50 to $200 for common varieties, with premiums for confirmed RPM varieties. However, the specific RPM-009 variety mentioned in the discussion would likely be valued closer to the price of any other ’43-D cent rather than commanding a significant premium.

Conclusion

The 1943-D/D RPM-3 Lincoln cent represents both a fascinating piece of American history and a challenging authentication puzzle for collectors. Whether you’re dealing with the RPM-003, RPM-009, or another variety, proper authentication requires attention to weight, magnetic properties, die markers, and awareness of common fakes.

Remember that even professional grading services can occasionally misidentify varieties, as suggested in the forum discussion where ANACS’s identification was questioned. Always cross-reference with authoritative sources like Variety Vista and consider seeking second opinions for valuable specimens. With proper knowledge and testing methods, you can confidently build your collection of these historic wartime cents.
