- Relatively low mintage numbers compared to other circulating coins
- Since 2009, the reverse design changes annually to commemorate Native American history and culture

Top 2010 Sacagawea Dollar Errors to Look For
1. Doubled Die Errors
Doubled die errors occur when the die strikes the planchet multiple times at slightly different angles, resulting in a doubling effect on design elements or inscriptions.
- Characteristics: Look for doubling on lettering, date, or portrait details
- Value Range: $100 – $2,000+ depending on severity and location
- Notable Example: A 2010-D MS62 Sacagawea dollar with a pronounced doubled die error on the date sold for $730 at a Heritage Auctions sale in 2018
Key Factors Affecting Value:
- Intensity of doubling
- Overall coin condition
- Location of the doubling (more prominent areas tend to command higher premiums)
2. Edge Lettering Errors
The Sacagawea dollar features edge lettering, which can sometimes be subject to errors during the minting process.
- Position B Error: Edge lettering appears upside-down in relation to the obverse portrait
- Missing Edge Lettering: Completely absent edge inscriptions
- Value Range: $50 – $1,500 depending on error type and condition
- Notable Example: A 2010-D MS65 Sacagawea dollar with a Position B edge lettering error sold for $1,100 at a Stack's Bowers auction in 2019
Collecting Tip: Always examine edge lettering carefully, as these errors can be subtle but valuable. Use a magnifying glass and good lighting for best results.
3. Lamination Errors
Lamination errors result from impurities in the metal alloy used to create the planchet.
- Characteristics: Can manifest as peeling, cracking, or splitting of the coin's surface
- Value Range: $50 – $2,000+ depending on severity and visual impact
- Notable Example: A 2010-P MS62 Sacagawea dollar with significant peeling on both obverse and reverse sold for $1,050 at a Great Collections auction in 2020
Grading Note: The severity and visibility of the lamination error greatly impact its value. More dramatic examples tend to command higher premiums.
4. Die Chip Errors
Die chip errors occur when small pieces of the die break off, leaving raised areas on the struck coin.
- Appearance: Small, raised bumps or irregularities on the coin's surface
- Value Range: $25 – $1,000+ depending on size and location
- Notable Example: A 2010-P MS60 Sacagawea dollar with a noticeable die chip error on Sacagawea's cheek sold for $880 at a Heritage Auctions sale in 2017
Collecting Strategy: Larger, more prominent die chips tend to be more valuable and easier to identify. Focus on areas with intricate design elements, as chips in these locations are often more desirable to collectors.
5. Die Crack Errors
Similar to die chips, die cracks form when the die develops fractures that then transfer to the struck coin.
- Characteristics: Raised lines on the coin's surface, often running across design elements
- Value Range: $20 – $1,500+ depending on size, location, and visual impact
- Notable Example: A 2010-D MS63 Sacagawea dollar with a significant die crack error running through the date sold for $555 at a Stack's Bowers auction in 2018
Market Insight: Die crack errors can vary widely in severity and value, with larger, more dramatic cracks commanding higher premiums. Collectors often seek out "cuds," where a section of the die has broken away completely, leaving a raised, blank area on the coin.
6. Missing Inscription Errors
In rare cases, coins may be struck with key inscriptions entirely absent.
- Example: 2010 Sacagawea dollars missing the "In God We Trust" inscription
- Value Range: $500 – $5,000+ depending on the missing inscription and overall condition
- Notable Example: A 2010-D MS64 Sacagawea dollar missing "In God We Trust" sold for $650 at a Heritage Auctions sale in 2019
Authentication Note: Be wary of artificially altered coins. Professional grading is strongly recommended for valuable missing inscription errors, as counterfeits do exist in the market.
7. Die Cap Errors
Die cap errors are among the most dramatic and visually striking minting errors.
- Cause: A planchet becomes stuck to the die and strikes multiple subsequent coins
- Appearance: Raised, bottle cap-like rim around the coin's edge
- Value Range: $500 – $5,000+ depending on severity and visual impact
- Notable Example: A 2010-D MS65 Sacagawea dollar with a pronounced die cap error sold for $1,200 at a Great Collections auction in 2021
Rarity Factor: Die cap errors are relatively uncommon, making them highly prized by error collectors. The more dramatic the cap formation, the higher the potential value.
8. Off-Center Strike Errors
Off-center strikes occur when the planchet is misaligned during the striking process.
- Characteristics: Design elements shifted towards one edge of the coin, often with missing portions
- Value Range: $50 – $2,500+ depending on the percentage off-center and visible design elements
- Notable Example: A 2010-P MS65 Sacagawea dollar with a 35% off-center strike on the obverse sold for $1,090 at a Heritage Auctions sale in 2020
Valuation Tip: The percentage of "off-centerness" directly impacts value, with more dramatic errors fetching higher prices. Coins that retain the full date despite being off-center are particularly desirable.
9. Rotated Die Errors
Rotated die errors happen when the obverse and reverse dies are misaligned during striking.
- Appearance: Reverse design rotated from its normal orientation relative to the obverse
- Value Range: $20 – $1,000+ depending on the degree of rotation
- Notable Example: A 2010-P MS64 Sacagawea dollar with a 180-degree rotated die error sold for $1,028 at a Stack's Bowers auction in 2019
Collecting Note: Minor rotations (less than 20 degrees) are relatively common; look for more dramatic misalignments for higher values. A 180-degree rotation, known as a "medal alignment," is particularly prized by collectors.
10. Strike-Through Errors
Strike-through errors occur when foreign material comes between the die and planchet during striking.
- Common Cause: Grease or debris on the die
- Characteristics: Weak or blurred design elements where the strike-through occurred
- Value Range: $20 – $500+ depending on size, location, and visual impact
- Notable Example: A 2010-D MS60 Sacagawea dollar with a notable grease strike-through error on the reverse sold for $435 at a Heritage Auctions sale in 2018
Identification Tip: Strike-through errors can sometimes be mistaken for wear; careful examination under magnification is crucial for proper identification.
