Two companies, one scale
Almost every graded gold coin you will see has been graded by one of two companies: the Professional Coin Grading Service (PCGS) or Numismatic Guaranty Company (NGC). Both use the Sheldon 1 to 70 scale, both seal coins in tamper evident holders, and both guarantee the authenticity of what they grade.
Background
- PCGS was founded in 1986 in California. It was the first of the major independent grading services and helped establish the sealed holder and the population report as industry standards.
- NGC was founded in 1987 in Florida. It has grown into the largest grading company by volume and is particularly strong in modern and world coins.
How their labels differ
| NGC | PCGS | |
|---|---|---|
| Proof grade | PF, as in PF70 | PR, as in PR70 |
| Strongest proof contrast | Ultra Cameo | Deep Cameo (DCAM) |
| Early release label | Early Releases, First Releases | First Strike |
| Population data | NGC Census | PCGS Population Report |
Verifying a graded coin
Every holder carries a certification number. Enter it on the grading company’s website and you should see the same coin, grade and details as the label, often with photographs. If the details do not match, or the holder is cracked or shows signs of tampering, do not rely on the grade.
Does one command a higher price?
Not universally. Preferences vary by market and by series, and the individual coin matters far more than the logo on the slab: its grade, population, eye appeal and demand. Judge each coin on its own merits.
Strengths of each
- PCGS: long established, especially strong in the American market, with a well known set registry for collectors.
- NGC: very large international following, strong in modern British and world coins, and linked to a respected coin conservation service.
Questions people ask

Neither outright. Both are trusted; the coin and its grade matter more.

Both mean Proof. It is simply each company’s abbreviation.
Can a coin graded by one be regraded by the other?
Yes, by crossing it over, though the grade is not guaranteed to stay the same.
How do I check a certification number?
Enter it on the NGC or PCGS website.
