NGC Modern Coin Classification 2 — Questions and Answers
Question 1: Which NGC designation indicates a coin was struck on a planchet intended for a different denomination?
- Wrong Planchet Error (Correct answer)
- Off-Center Strike
- Broadstrike
- Die Cap
Correct answer: Wrong Planchet Error
A Wrong Planchet Error occurs when a coin is struck on a planchet prepared for a different denomination or series.
Question 2: In NGC's grading system, what does the prefix 'PF' (or 'PR') indicate about a modern coin?
- Proof finish struck for collectors (Correct answer)
- Pre-Federal issue
- Partially frosted surfaces
- Professional Refinery origin
Correct answer: Proof finish struck for collectors
PF (or PR) designates a Proof coin, meaning it was specially struck using polished dies and planchets for collector use.
Question 3: What distinguishes a Burnished (BN) coin from a standard Uncirculated coin in NGC's classification?
- It is burnished by hand before striking
- The planchet is burnished before striking giving a unique satin-like finish (Correct answer)
- It has been cleaned after striking
- It features reverse proof surfaces
Correct answer: The planchet is burnished before striking giving a unique satin-like finish
Burnished coins, such as American Eagle Burnished issues, have planchets that are burnished before striking, producing a satin or matte-like surface distinct from standard business strikes.
Question 4: Which modern U.S. Mint product is classified by NGC as 'SP' (Specimen)?
- West Point Mint bullion coins with special finishes (Correct answer)
- Standard circulating quarters
- Proof sets sold at face value
- Uncirculated rolls from the Federal Reserve
Correct answer: West Point Mint bullion coins with special finishes
NGC uses the SP designation for coins such as certain American Eagle issues with special finishes that don't meet the strict Proof definition but exceed standard business strike quality.
Question 5: How does NGC classify a modern commemorative coin that was never released and remains in original U.S. Mint packaging?
- MS or PF depending on its strike type (Correct answer)
- Specimen (SP)
- First Strike only
- PR-69 automatically
Correct answer: MS or PF depending on its strike type
NGC grades modern commemoratives as either MS (Mint State) if business-strike quality or PF (Proof) if struck as a proof, regardless of whether packaging is intact.
Question 6: What NGC label designation acknowledges a coin submitted within a specific early release window set by the U.S. Mint's official sale date?
- First Day of Issue
- Early Releases (Correct answer)
- Premiere Edition
- Original Strike
Correct answer: Early Releases
NGC's Early Releases label is awarded to coins submitted within 30 days of the U.S. Mint's official release date, distinguishing them as among the first distributed.
Question 7: A 2021 Morgan Silver Dollar with a 'CC' privy mark released by the U.S. Mint would be classified under which NGC category?
- Modern commemorative issue (Correct answer)
- Classic Morgan Dollar
- Bullion coin
- Error coin
Correct answer: Modern commemorative issue
The 2021 Morgan Silver Dollars are classified as modern commemorative issues because they are new legal-tender coins honoring a historic design, not continuations of the original series.
