Overgrading is a risk in rare coin purchases, where a coin’s condition is represented as better than it truly is. Edison buyers can protect themselves by learning to spot signs of inflated grades.

Watch for:

• Mismatch between grade and appearance – A coin labeled high-grade should show minimal wear.
• Lack of third-party certification – Certified coins from PCGS or NGC offer trusted grading.
• Unclear or missing documentation – Honest dealers provide full records with each coin.
• Suspiciously high pricing – Inflated grades often accompany inflated prices.
• Reluctance to provide close-up images or inspections – Transparency is key in rare coin sales.

Being aware of these signs helps Edison buyers make confident, well-informed rare coin purchases.
