Introduction & Value Overview
In the realm of numismatics, few coins capture the essence of Civil War America like the 1864 Indian Head Penny. A remarkable transition year specimen, this coin commands impressive values in today’s market, with pristine examples regularly fetching $5,000 to $10,000. Recently, a PCGS MS-66+ RD example shattered expectations when it realized $26,400 at Heritage Auctions—demonstrating the exceptional premium collectors place on top-grade specimens of this historical transition year cent.
The 1864 Indian Head Penny represents a pivotal moment in American coinage history, as the Mint transitioned from copper-nickel to bronze composition mid-year in response to metal shortages during the Civil War. This transition created two distinct varieties—the early-year copper-nickel and the later bronze version—each carrying significant value implications for modern collectors.
This guide provides comprehensive value assessment across all grades and varieties, from circulated examples worth $12-15 to the rare uncirculated specimens commanding thousands. We’ll explore how mint marks, composition varieties, and striking errors dramatically impact the 1864 Indian Head Penny’s worth in today’s competitive market.

Authentication Markers
Genuine 1864 Indian Head Pennies display several critical diagnostic features. The headdress feathers show distinct separation between quills, with the lowest feather positioned slightly above the date. The ear is well-defined, displaying a raised inner ear design. The profile should demonstrate precise, clean edges without any flow lines that might suggest casting.
For the bronze variety, authenticate by examining the “L” on the ribbon behind the neck—a feature added by designer James Longacre during the composition change. This small letter appears on many (but not all) bronze examples.
Design Elements
The obverse features Lady Liberty wearing a Native American headdress with “LIBERTY” inscribed on the band. The date “1864” appears below the portrait, with 13 stars surrounding the periphery.
The reverse presents an oak wreath encircling the words “ONE CENT,” with the denomination prominently centered. Above the wreath sits a small shield, with “UNITED STATES OF AMERICA” following the upper rim.
Designer Information
James Barton Longacre served as Chief Engraver of the United States Mint from 1844 until his death in 1869. His 1864 addition of the “L” initial to bronze versions of the Indian Head Penny represents one of the earliest instances of a designer’s mark on regular U.S. coinage—a feature that dramatically affects value today. Longacre’s modification came at a pivotal moment in American numismatic history, as the Mint adjusted to wartime metal shortages by reducing the cent’s weight and changing its composition.
Mint Mark Guide & Value Comparison
Mint Mark Locations
Unlike later Indian Head cents, the 1864 penny was produced exclusively at the Philadelphia Mint and therefore bears no mint mark. This simplifies attribution but places greater emphasis on composition varieties and striking characteristics for value determination.
Mint Mark Value Comparison
Since all 1864 Indian Head Pennies were struck in Philadelphia, there is no mint mark comparison table. However, the composition difference creates a significant value divergence:
| Variety | G-4 | F-12 | VF-20 | XF-40 | AU-50 | MS-60 | MS-63 RD | MS-65 RD |
|---|---|---|---|---|---|---|---|---|
| Copper-Nickel | $15 | $35 | $85 | $150 | $250 | $400 | $1,000 | $6,000+ |
| Bronze (No L) | $12 | $25 | $65 | $120 | $225 | $350 | $900 | $4,500+ |
| Bronze with L | $20 | $45 | $100 | $175 | $300 | $600 | $1,500 | $7,500+ |
Mintage Figures
The 1864 Indian Head Penny saw production across two compositions:
- Copper-Nickel: Approximately 13.3 million pieces
- Bronze: Approximately 39.2 million pieces (including both with and without “L”)
The bronze varieties significantly outnumber their copper-nickel counterparts, though the “L” on ribbon variety represents only a portion of the bronze production (exact figures unknown), contributing to its premium value.
Most Valuable Variety
The Bronze with “L” variety commands the highest premium among 1864 Indian Head Pennies, particularly in Mint State red condition. This elevated value stems from the historical significance of Longacre’s initial, its limited production window (late 1864 only), and the stunning visual appeal of well-preserved examples that maintain their original mint luster.

Price Trend Analysis
The 1864 Indian Head Penny market has demonstrated consistent strength over the past decade, with particularly significant growth in high-grade certified examples. The bronze “L” variety has appreciated approximately 40% in MS-65 RD condition since 2015, outperforming many other Indian Head dates.
Copper-nickel examples, while less visually striking than their bronze counterparts, have shown even stronger investment performance due to their historical significance as the final copper-nickel cents before the composition change. Top-grade specimens have appreciated nearly 60% over the past decade.
Condition Impact
The value progression between grades demonstrates extraordinary premium jumps at certain threshold points:
- From AU-50 to MS-60: 60-100% increase (preservation of mint luster)
- From MS-63 BN to MS-63 RD: 65-90% increase (color designation premium)
- From MS-63 RD to MS-65 RD: 400-500% increase (gem quality premium)
These dramatic value increases underscore the importance of proper grading and preservation for investment-quality specimens.
Key Date Analysis
While the 1864 is not considered the rarest date in the Indian Head series, its historical significance as a wartime transitional issue establishes it as a key date by collector demand. Among 1864 varieties, the bronze with “L” commands consistent premium pricing approximately 50-75% higher than the no-L bronze variety across all grades.

Major Error Types & Their Values
Off-Center Strikes
Off-center 1864 Indian Head Pennies range from minor (5-10% off-center) to dramatic (40-50% off-center while still showing the date). Authentication characteristics include intact rims on the portion of the coin that received the strike and a tapering blank area where the strike missed.
Values range significantly based on severity:
- 5-10% off-center: $150-300
- 20-30% off-center: $600-1,200
- 40-50% off-center with visible date: $2,000-3,500
Extreme off-centers (50%+) that still display the complete date are exceptionally rare for 1864 and may command $5,000+ when authenticated.
Clipped Planchets
Planchet clips occur when the cutting die overlaps a previously cut area or strikes the edge of the metal strip. These errors appear as missing segments along the coin’s edge, typically in curved or straight formations.
For 1864 Indian Head Pennies, clip errors carry significant premiums:
- 5-10% straight clip: $150-300
- 10-20% curved clip: $300-600
- Multiple clips: $800-1,500
Authentication requires verification that the flow lines near the clip are distorted appropriately—indicating the error occurred during minting rather than through post-mint damage.
Doubled Dies
The most valuable 1864 Indian Head Penny errors are doubled die varieties. While not as dramatic as some later dates, several notable doubled dies exist:
1864 Bronze Doubled Die Obverse (DDO-001)
- Visible doubling on LIBERTY and date
- Current values: $500 (VF) to $3,000+ (MS-63)
- Authentication points: Consistent doubling direction and appropriate separation
1864 Copper-Nickel Doubled Die Reverse (DDR-002)
- Doubling visible on ONE CENT and lower wreath elements
- Current values: $400 (VF) to $2,500+ (MS-63)
- Rarity: Fewer than 100 examples confirmed
Die Breaks and Cuds
Late-die state 1864 cents with significant die breaks or cuds (missing sections of design where pieces of the die have broken away) carry substantial premiums:
- Minor die cracks: $50-150 premium
- Major die breaks affecting lettering: $200-500 premium
- Large cuds (15% or more of rim area): $600-1,200 premium
The most valuable cud errors connect to significant design elements like the date or LIBERTY, which can command $1,500+ in higher grades.
Wrong Planchet Errors
Exceptionally rare are 1864 Indian Head cents struck on incorrect planchets. These include:
- Struck on silver three-cent planchet: $15,000-25,000
- Struck on two-cent piece planchet: $10,000-15,000
- Struck on foreign coin planchet: $5,000-10,000
Authentication requires proper weight verification and compositional analysis, as these extraordinary errors are frequently counterfeited.
