How do I know if my coin is a rare variety?
Research and compare
Start by identifying the date, mintmark, and design type. Then use reference books like the Red Book, Cherrypickers' Guide, or online resources like PCGS CoinFacts to see if a variety is listed for that issue.
Look for specific die markers such as doubled letters, repunched mintmarks, or misplaced digits. These markers are unique to the die and confirm the variety.
Check rarity and demand
Rarity is determined by how many examples are known. Some varieties are common (e.g., 1972 doubled die cent) while others are extremely rare (e.g., 1969-S doubled die cent). Mintage figures and survival rates affect rarity.
Demand also plays a role: a variety may be rare but not popular, so value may be lower. Check auction records and population reports from grading services to gauge rarity and market interest.
Professional attribution
If you suspect a rare variety, submit it to a grading service like PCGS, NGC, or ANACS for attribution and grading. They will confirm the variety and encapsulate it, which adds credibility and value.
Joining collector forums or clubs can also help; experienced collectors can often identify varieties from photos. However, always rely on authoritative references for final confirmation.
- Use the Cherrypickers' Guide or Red Book for listings.
- Look for die markers like doubling or repunched mintmarks.
- Check population reports for known examples.
- Submit to a grading service for official attribution.
- Consult collector communities for opinions, but verify with references.
Common mistakes
- Assuming any doubled appearance is a rare variety; many are common or just machine doubling.
- Relying solely on online images without checking die markers.
- Ignoring the importance of mintmark and date combinations that can indicate rarity.
