1943 Steel Penny Error List with Pictures & Value
The 1943 steel penny represents a unique chapter in American numismatics. During World War II, copper was needed for ammunition production, leading the U.S. Mint to produce pennies from zinc-coated steel. While over one billion were minted, several 1943 steel penny error varieties have become highly valuable to collectors. Understanding these errors, from copper planchet mistakes to die cracks, helps collectors identify potentially valuable coins. For comprehensive information about standard 1943 steel penny value, collectors should research authenticated examples and current market trends.
1943 Steel Penny Copper Planchet Error
The most famous and valuable 1943 steel penny error is actually a copper penny struck by mistake. When the Mint transitioned from copper to steel production in 1943, a few leftover copper planchets from 1942 remained in the presses. These blanks were accidentally struck with 1943 dies, creating one of the most sought-after errors in American numismatics. Examples exist from all three mints: Philadelphia (no mintmark), Denver (D), and San Francisco (S).
Value Range: $100,000 to $1,700,000+ depending on mint, grade, and color designation. The 1943-S copper penny is the rarest, with only one confirmed example. The 1943-D copper penny is also extremely rare with only one known specimen. Philadelphia examples are most common but still extraordinarily valuable, with approximately 20-22 confirmed specimens known.
Identification Tips: Copper pennies do NOT stick to a magnet (steel pennies do). Weight is critical: copper pennies weigh 3.11 grams while steel pennies weigh 2.7 grams. Copper pennies have a reddish-brown color rather than silvery appearance. Beware of counterfeits: copper-plated steel pennies are common fakes that will still stick to magnets.

1943 Steel Penny Off-Center Strike Error
Off-center strike errors occur when the blank planchet is not properly aligned in the coining press during striking. This misalignment causes part of the design to be missing, with a corresponding blank crescent-shaped area visible on the coin. The degree of misalignment determines the value, with more dramatic off-center strikes commanding higher premiums. These errors are relatively common compared to copper planchet errors but still desirable to collectors.
Value Range: $10 to $500+ depending on the percentage off-center and coin condition. Minor off-center strikes (5-10%) typically sell for $10-$25. Moderate off-center strikes (25-35%) range from $50-$150. Dramatic off-center strikes (50% or more) can bring $200-$500 or more, especially in uncirculated condition.
Identification Tips: Look for a blank crescent area where no design appears. The date should be fully visible for maximum value. Check that the coin still has its complete rim. Measure the percentage off-center by estimating what portion of the design is missing. Coins struck completely off the planchet (100% off-center) on blank planchets are extremely rare and valuable.

1943 Steel Penny Die Crack and Cud Error
Die cracks and cud errors resulted from the brittleness of steel cent dies used in 1943. As dies struck hundreds of thousands of coins, stress caused cracks to form in the die surface. These cracks appear as raised lines on struck coins. When a piece of the die actually broke away, it created a "cud" - a raised blob of metal on the coin where the broken die area could not properly strike the design. The 1943 steel cent dies were particularly prone to these failures.
Value Range: $50 to $500+ depending on the size and location of the crack or cud. Minor die cracks typically sell for $50-$100. Medium-sized cracks affecting major design elements range from $100-$250. Large cud errors, especially those affecting the date or major portions of the design, can bring $300-$500 or more in high grades.
Identification Tips: Die cracks appear as raised lines (not incused scratches) on the coin surface. Cuds appear as raised, unstruck blobs, usually along the rim. The crack or cud should be consistent across multiple examples if from the same die. Distinguish from damage by checking if the line is raised and follows a natural crack pattern. Major cuds affecting lettering or dates are most valuable.

1943 Steel Penny Repunched Mintmark Error
Repunched mintmark (RPM) errors occurred when mint workers hand-punched the D or S mintmark into the working die multiple times in slightly different positions. This created a doubled or tripled mintmark appearance. Several RPM varieties exist for both the 1943-D and 1943-S steel pennies. These errors are collected by specialists who study and catalog the specific doubling characteristics of each variety.
Value Range: $25 to $21,000+ depending on the variety and grade. Common RPM varieties in circulated condition sell for $25-$75. Strong RPM varieties in uncirculated condition range from $100-$500. The most dramatic 1943-S RPM varieties in gem condition have sold for over $21,000 at auction. The 1943-D/D varieties are also collected and valued based on the strength of the repunching.
Identification Tips: Use magnification to examine the D or S mintmark below the date. Look for doubling, tripling, or extra metal around the mintmark edges. Compare to known RPM variety images in error coin references. Strong RPMs show clear separation between the primary and secondary mintmark punches. Weak RPMs may only show slight notching or thickening of mintmark elements.

1943 Steel Penny Double Strike Error
Double strike errors occur when a coin is struck by the dies twice, creating overlapping images. The second strike may be perfectly aligned (in-collar) or rotated/shifted from the first strike (out-of-collar). The most dramatic examples show two completely offset images. Double strikes should not be confused with doubled dies, which are hub doubling errors that affect all coins from that die. True double strikes are individual coins that received two separate blows from the press.
Value Range: $200 to $1,000+ depending on the degree of separation and condition. Weak double strikes with minimal separation sell for $200-$400. Strong double strikes with clear second image offset by 10-50% range from $500-$800. Dramatic double strikes with 75%+ offset can bring $1,000 or more, especially in uncirculated condition.
Identification Tips: Look for complete doubling of the entire design rather than just specific areas. Check if the doubling shows rotation between strikes. Genuine double strikes show spreading metal at the rim from multiple compressions. Use magnification to verify two distinct strike impressions. Compare to images of known double strike errors to confirm authenticity.

1943 Steel Penny Strike-Through Error
Strike-through errors occur when foreign material such as grease, cloth fragments, or debris gets between the die and planchet during striking. This material prevents the design from being fully transferred, leaving weak or missing design elements. The most common strike-through error on 1943 steel pennies is filled die (grease-filled die), where grease accumulates in recessed die areas. This often affects letters in LIBERTY or details in the wheat stalks.
Value Range: $10 to $100 depending on the severity and location. Minor strike-throughs affecting one or two letters typically sell for $10-$25. Moderate strike-throughs affecting multiple design elements range from $30-$60. Major strike-throughs leaving significant portions of the design weak or missing can bring $75-$100 or more. Unusual strike-through materials (cloth, wire) command premiums.
Identification Tips: Look for weak, incomplete, or missing design elements with smooth surfaces (not worn). Strike-throughs typically affect recessed design areas (letters, date numbers). The affected area should show consistent weakness or absence across the struck impression. Distinguish from wear by checking high points - wear affects high points first, strike-throughs affect low areas. Original mint luster should be present in strike-through areas.

1943 Steel Penny Missing Zinc Coating Error
The 1943 steel pennies were made from low-carbon steel coated with zinc to prevent rust. Some pennies did not receive proper zinc coating during the plating process, either partially or completely. These uncoated pennies quickly developed rust and corrosion when exposed to moisture, giving them a reddish or brown appearance rather than the normal silvery look. While interesting errors showing the production process, they are generally less valuable than other major errors unless in exceptional condition.
Value Range: $5 to $75 depending on the extent of missing coating and preservation. Partially uncoated examples with minimal rust sell for $5-$15. Completely uncoated examples showing even rust patina range from $20-$40. Well-preserved examples showing original uncoated steel surface without heavy rust can bring $50-$75 to specialists. Heavily rusted examples have minimal value.
Identification Tips: Look for reddish-brown rust coloration rather than silvery zinc. Check if the coin still attracts a magnet (confirms steel core). Examine for uniform coating loss versus localized areas. Original uncoated steel appears darker gray. Distinguish from environmental damage - missing zinc coating shows from the moment of striking. Compare weight to standard (2.7 grams) to confirm steel composition.
