About NGC

NGC (Numismatic Guaranty Company) is the world's largest third-party coin grading service by volume. Founded in 1987 and headquartered in Sarasota, Florida, NGC is a subsidiary of Certified Collectibles Group (CCG). NGC has graded hundreds of millions of coins from virtually every country and time period.

What NGC Is Known For

While NGC grades US coins to the same high standard as PCGS, NGC is particularly well regarded for world coins, ancient coins, and tokens. Their World Coin Census and Ancients Census are industry-leading databases that track grading populations for non-US coins — something no other grading service matches in depth.

NGC also offers specialized services including variety attribution, conservation (NCS — Numismatic Conservation Services), and custom labels for special coin issues.

Submission Tiers and Pricing

  • Economy — $22–$30/coin, 30+ business days, coins valued under $3,000
  • Standard — $40–$50/coin, 15–20 business days
  • Express — $75–$100/coin, 5–10 business days
  • Walkthrough — $150+/coin, 1–3 business days

NGC membership starts at $25/year for the basic tier, which is more affordable than PCGS for casual submitters. Submissions can also be made through authorized dealers or at coin shows.

NGC Guarantee

NGC guarantees the authenticity and grade of every coin they certify. If an NGC-graded coin is found to be counterfeit or overgraded, NGC will buy it back at fair market value. This guarantee covers the coin as long as it remains in the original, unaltered NGC holder.
