The 2001 New York State Quarter is iconic in the 50 States Quarters series, featuring the Statue of Liberty and issued in est. 619 million pieces from Philadelphia and 655 million from Denver.
Yet, among this mass production, a few hidden error varieties slipped out, unknown to most collectors—making them coveted treasures today.
Error Type 1: Retained Strike-Through (Struck-Through Debris)
During minting, foreign debris (fabric, grease, metal) can become trapped between the die and planchet. If it remains embedded during striking, the result is a retained strike-through, leaving a raised absence of detail where it lay.
- 2001-D New York Quarter examples with these errors have been graded MS67 and command hundreds to over $500 in today’s market.
- The error is dramatic—missing letters, date flaws, or Liberty outline disruptions due to foreign object blockage.
Error Type 2: Folded Overstrike
Misfeeds in the feed system can cause the blank to fold under pressure. This produced a folded overstrike error quarter: part of the die engraved design appears doubled or folded.
- 2001-P examples, graded as high as MS68, have sold for approximately $300–$400.
Error Type 3: Dual Planchet Strike (Double Disc Strike)
Occasionally, two overlapping planchets are struck simultaneously, resulting in coins split or partially struck.
- 2001-D New York quarters with this dual planchet error sometimes exceed $400 for high-grade specimens.
Lesser-Known Errors: Misaligned Die, Die Chips, & Missing Letters
- Misaligned die (MAD): Strike off-center due to tilted die. Adds visual interest, but limited premium.
- Die chips (cuds, gouges): Raised blobs or gouges from die fracture or wear. Several listings describe notable die gouge errors on 2001-P examples, with prices from $50–$150.
- Missing letters: Grease-filled dies from the mint lead to missing letters like “R” in DOLLAR. Popular in online forums, though not always valuable.

| Missing Letter (“Dolla”) | VF–EF | $10–$50 | Niche interest; often dismissed as grease |
Why These Errors Occurred
Understanding mint processes helps explain these errors:
- Retained debris: Foreign materials adhere to the planchet; the high-pressure strike embeds them instead of producing clean designs.
- Folded planchets: Misfeed causes blanks to fold during striking.
- Dual strikes: Planchets overlap in hopper → simultaneous imprinting.
- Die wear/chips: Used dies crack or chip, transferred onto subsequent strikes.
- Grease-filled dies: Oil blocks recessed areas, producing missing letters .
Finding These Hidden Gems in Circulation
- Study minting details: Know the standard design—e.g., number of fingers, letter presence, edge reeding.
- Use magnification: Inspect the device on button, date, and lettering for irregularities.
- Look for texture anomalies: Raised blank patches or folds.
- Check edges/collars: Misfeeds or broadstrikes affect edge texturing.
- Submit for grading: PMG or PCGS certification confirms and promotes value.
Why Collectors Are Drawn to These Errors
- Scarcity: Only a fraction of millions minted show these anomalies.
- Visual impact: Obvious flaws deliver visual intrigue.
- Provenance through grading: Certification guarantees authenticity and secures value.
- Affordability: Compared to higher-value coins, these errors appeal to mid-tier collectors.
