1776 to 1976 Dollar Error List with Pictures & Value

The 1776 to 1976 dollar error list encompasses several remarkable varieties and minting mistakes from the Bicentennial Eisenhower dollar series. These commemorative coins celebrating America's 200th anniversary include valuable Type 1 and Type 2 varieties, the legendary No S Proof, off-center strikes, and wrong planchet errors. Understanding 1776 to 1976 silver dollar value requires knowledge of these distinct error categories.

1776 to 1976 Dollar Type 1 vs Type 2 Variety

The Type 1 and Type 2 varieties represent the most widespread distinction among Bicentennial Eisenhower dollars. These are not errors in the traditional sense but rather design modifications made early in production. The United States Mint began striking 1776-1976 Bicentennial dollars in 1975, and modifications to the reverse lettering came soon after the first coins rolled off the presses.

Type 1 dollars feature blocky, bold, sans-serif lettering on the reverse inscriptions UNITED STATES OF AMERICA and ONE DOLLAR. This original design was modified because it did not facilitate optimal striking quality on clad planchets. Type 2 dollars display refined lettering with serifs that closely resemble the font style used on the obverse of standard Eisenhower dollars. The transition occurred early in 1975, making Type 1 business strikes considerably scarcer than Type 2, particularly from the Philadelphia Mint.

Value Range

Type 1 Philadelphia (no mint mark): $35 to $500 in high grades

Type 1 Denver (D mint mark): $25 to $200 in high grades

Type 2 coins: Face value to $50 depending on condition

Type 1 Silver (S mint mark): All 40% silver Bicentennial dollars are Type 1, valued $15 to $100+

Identification Tips

  • Examine the reverse lettering style under good lighting or magnification
  • Type 1 letters appear thicker, bolder, and blockier without decorative strokes
  • Type 2 letters are thinner and feature small serifs at the ends of strokes
  • Compare multiple coins side-by-side to see the contrast clearly
  • Type 1 Philadelphia coins were primarily distributed in mint sets
  • All 40% silver dollars have Type 1 reverse design exclusively

1776 to 1976 Dollar No S Proof Error

The 1776-1976 No S Proof Type 2 Bicentennial dollar stands as perhaps the most significant modern U.S. coin rarity. Only one specimen is known to exist, making it extraordinarily valuable and historically important. This unique coin was struck at the Philadelphia Mint as a trial piece during the design modification process from Type 1 to Type 2.

On August 12, 1974, the three winning designers of the Bicentennial coins were permitted to strike trial proof coins at the Philadelphia Mint. Since these trial pieces were produced in Philadelphia rather than San Francisco, they did not receive the S mint mark standard on all other proof Bicentennial dollars. While Type 1 No S trial proofs were made for presentation purposes, the existence of a Type 2 No S proof suggests that Chief Engraver Frank Gasparro may have struck trial pieces to evaluate the new refined lettering design.

Value Range

1776-1976 No S Proof Type 2: Estimated $850,000 or more

Status: Unique specimen, graded PCGS PR66CAM

Current ownership: Mitchell Spivack private collection

Identification Tips

  • Must exhibit proof characteristics: mirror-like fields and frosted devices
  • Check for Type 2 reverse with refined, thin lettering featuring serifs
  • Verify complete absence of any mint mark below Eisenhower's neck
  • Proof coins should show no circulation wear and exceptional strike quality
  • Authentic proofs have sharp, squared rims and pristine surfaces
  • Professional authentication absolutely essential for any suspected No S proof
  • Be aware that Philadelphia circulation strikes normally have no mint mark

1776 to 1976 Dollar Off-Center Strike Error

Off-center strike errors occur when the planchet is not properly positioned between the dies during the striking process, resulting in a portion of the design missing and a corresponding blank crescent-shaped area visible on the coin. For Bicentennial dollars, off-center strikes are dramatic errors that command significant premiums, especially when the dual date 1776-1976 remains fully visible.

A notable example sold at auction in 2016 demonstrates the value of these errors. The specimen was struck approximately 30% off-center and also exhibited broadstrike characteristics, meaning it was struck without the collar die in place. This allowed the metal to flow beyond normal boundaries, creating an expanded diameter of 42 millimeters instead of the standard 38 millimeters. The combination of off-center misalignment and broadstrike features makes such errors particularly desirable to collectors.

Value Range

Minor off-center (5-15%): $100 to $400

Moderate off-center (20-35%): $500 to $2,000

Dramatic off-center (40%+ with date): $2,500 to $7,500

Broadstrike combination: Additional premium of 50-100%

Identification Tips

  • Look for a blank, curved area showing the original planchet surface
  • The design should be cleanly cut off, not worn or damaged away
  • Both obverse and reverse should show consistent off-center alignment
  • Verify that the date remains visible for maximum value
  • Check for expanded diameter indicating broadstrike characteristics
  • Estimate the off-center percentage by measuring visible rim
  • Edge reeding may be incomplete or absent on broadstruck examples

1776 to 1976 Dollar Wrong Planchet Error

Wrong planchet errors represent some of the most valuable Bicentennial dollar mistakes. The most significant involves 1976-D dollars struck on 40% silver planchets intended for San Francisco production. These errors occurred when silver planchets from San Francisco were accidentally shipped to and mixed with clad planchets at the Denver Mint. The wrong metal composition creates a coin that weighs 24.6 grams instead of the normal 22.7 grams for copper-nickel clad dollars.

Only two examples of 1976-D Bicentennial dollars struck on 40% silver planchets are known to exist, making them extraordinarily rare. One was certified AU58 and the other Mint State. While there are an estimated 45 known Denver Mint 40% silver Eisenhower dollars from other years (primarily 1974-D and 1977-D), the 1976-D date is exceptionally scarce. Reports also mention three known 1972-D examples on silver planchets, but the Bicentennial date's rarity makes it especially coveted.

Value Range

1976-D on 40% silver planchet: $10,000 to $30,000+

Known population: Only 2 examples

Other wrong planchet errors: $500 to $5,000 depending on type

Identification Tips

  • Weigh the coin precisely - silver planchets weigh 24.6g vs 22.7g for clad
  • Silver coins have a distinct sound when tapped compared to clad
  • Examine the edge for silver cladding layers versus copper core visibility
  • Silver planchets have slightly different luster and color tone
  • Must have D mint mark for the rarest wrong planchet variety
  • Professional authentication and weighing essential for verification
  • Be aware that silver-plated coins are worthless alterations, not mint errors

Frequently Asked Questions

What are the most valuable 1776 to 1976 dollar errors?
The most valuable 1776 to 1976 dollar error is the No S Proof Type 2, with only one known specimen valued at approximately $850,000. The 1976-D struck on 40% silver planchet is extremely rare with only two known examples worth thousands. Off-center strikes with visible dates can reach $7,000, while Type 1 varieties from Philadelphia in high grades command $100 to $500 premiums. Regular doubled die and filled mint mark errors typically range from $50 to $300. Use the CoinValueChecker app to quickly assess whether your Bicentennial dollar has any of these valuable errors.
How can I tell if my 1776 to 1976 dollar is Type 1 or Type 2?
The difference between Type 1 and Type 2 is in the reverse lettering style. Type 1 features blocky, bold, sans-serif letters in UNITED STATES OF AMERICA and ONE DOLLAR. Type 2 has thinner, refined lettering with serifs that matches the obverse font style more closely. Examine the reverse inscription closely under good lighting - Type 1 letters appear thicker and bolder, while Type 2 letters are more delicate with small decorative strokes at the ends. The CoinKnow app includes side-by-side comparison images to help you accurately identify which type you have.
What is the 1976 No S Proof dollar worth?
The 1976 No S Proof Type 2 Bicentennial dollar is extraordinarily rare, with only one known example. It was graded PCGS PR66CAM and is estimated to be worth approximately $850,000 or more. This coin was struck at the Philadelphia Mint as a trial piece before production moved to San Francisco. It lacks the S mint mark that appears on all other proof Bicentennial dollars. Due to its unique status as possibly the rarest modern U.S. coin, its value could exceed even this estimate at auction. The CoinValueChecker app can help you verify if you have a proof coin, though finding this specific error is extremely unlikely.
Are 1776 to 1976 dollars with no mint mark valuable?
Most 1776 to 1976 dollars without mint marks are common Philadelphia circulation strikes worth face value to a few dollars in circulated condition. However, Type 1 varieties from Philadelphia are scarcer than Type 2 and can be worth $35 to $100 in high grades. The key exception is the unique No S Proof Type 2, worth hundreds of thousands. Regular Philadelphia dollars in MS65 or better can fetch $20 to $100 depending on quality. Always check the reverse lettering style to determine if you have the scarcer Type 1 variety. The CoinKnow app helps distinguish valuable Philadelphia varieties from common circulation strikes.
How do I identify an off-center 1776 to 1976 dollar error?
An off-center strike shows a portion of the design missing with a corresponding blank curved area on the coin. The misalignment should be obvious, with part of the rim and design elements clearly absent. Check that both sides show consistent off-center alignment in the same direction. Authentic off-center errors have sharp, clean edges where the design cuts off, not worn or damaged edges. The most valuable examples are 20% or more off-center but still show the full date. Some off-center Bicentennial dollars also exhibit broadstrike characteristics with expanded diameters. The CoinValueChecker app includes measurement guides to help you determine the off-center percentage.
What is a 1976-D dollar struck on a silver planchet?
A 1976-D struck on a 40% silver planchet is an extremely rare wrong planchet error where a Denver-minted clad dollar was accidentally struck on a silver planchet intended for San Francisco production. Only two examples dated 1976-D are known to exist. These coins weigh 24.6 grams instead of the normal 22.7 grams for clad versions. The error occurred when silver planchets from San Francisco were accidentally mixed with Denver's clad planchets. This wrong metal error is one of the most valuable Bicentennial dollar mistakes, worth thousands of dollars. The CoinKnow app provides weight specifications to help identify potential wrong planchet errors.
Where is the mint mark located on 1776 to 1976 dollars?
The mint mark on 1776 to 1976 Bicentennial dollars appears on the obverse (front) below Eisenhower's neck, between the bottom of his truncated bust and the digits 9 and 7 in the date 1976. Denver-minted coins show a D, while San Francisco coins display an S. Philadelphia-minted coins have no mint mark, as was standard before 1980. The mint mark is small but clearly visible under normal lighting. Proof coins should always have an S mint mark unless you have discovered the extremely rare No S Proof error. The CoinValueChecker app includes detailed images showing exact mint mark placement for easy verification.
What makes a 1776 to 1976 dollar a proof coin?
Proof coins have mirror-like fields and frosted devices, creating sharp contrast between design elements and background. They were struck multiple times with specially polished dies and planchets, resulting in exceptionally detailed strikes. Proof Bicentennial dollars were sold in special sets, never released into circulation, and should show no wear. They have a distinctly different appearance from business strikes - shinier, sharper, and more reflective. All proof Bicentennial dollars should have an S mint mark except for the unique No S error. If you find a coin with proof-like qualities but no mint mark, professional authentication is essential. The CoinKnow app explains the visual differences between proof and business strike coins.
Are there doubled die varieties in 1776 to 1976 dollars?
Yes, doubled die varieties exist for Bicentennial dollars, though they are not as dramatic or common as in some other series. Doubling typically appears on the date digits, LIBERTY lettering, or elements of the Liberty Bell design on the reverse. True doubled dies show clear separation and doubling of devices, not the shelf-like appearance of strike doubling. Most doubled die Bicentennial dollars are minor and worth $50 to $300 depending on the strength of doubling and coin grade. Significant doubled dies affecting multiple design elements can command higher premiums. The CoinValueChecker app helps distinguish genuine doubled dies from machine doubling and other less valuable anomalies.
How should I store valuable 1776 to 1976 dollar errors?
Store valuable error coins in archival-quality holders such as non-PVC flips, air-tite capsules, or certified grading service slabs. Avoid touching the coin surfaces directly - always handle by the edges. Keep coins in a climate-controlled environment away from humidity, extreme temperatures, and direct sunlight. For high-value errors like off-center strikes or wrong planchet pieces, professional grading and encapsulation by PCGS or NGC provides both protection and authentication. Never clean coins, as this destroys value. Store horizontally to prevent sliding within holders. Document your coins with photographs and keep provenance records. The CoinKnow app can help you track your collection and maintain detailed records of your error coins.

Summary

Bicentennial Eisenhower dollars from 1776 to 1976 present collectors with diverse error opportunities ranging from common design varieties to extraordinarily rare mint mistakes. Type 1 versus Type 2 distinctions affect millions of coins, with Type 1 Philadelphia examples commanding $35 to $500 premiums in superior grades due to lower mintages. The unique 1976 No S Proof Type 2 represents the pinnacle of modern coin rarity, valued near $850,000 as the only known specimen. Off-center strikes create visually dramatic errors worth $100 to $7,500 depending on misalignment severity and whether the date remains visible, with broadstrike combinations adding substantial premiums. Wrong planchet errors achieve exceptional values, particularly the two known 1976-D dollars struck on 40% silver planchets intended for San Francisco, worth $10,000 to $30,000 each. Additional collectible varieties include doubled dies, filled mint marks, and die cracks that add moderate premiums of $50 to $300. Proper identification requires careful examination of reverse lettering styles, accurate weight measurements, and verification of proof characteristics versus circulation strikes. Mobile applications like CoinValueChecker and CoinKnow provide essential tools for authentication, valuation, and market research. Professional grading services offer definitive authentication for high-value errors and protect investment quality through secure encapsulation.
