What do PCGS and NGC mean?

PCGS and NGC are major third-party grading services. They authenticate, grade, and seal coins in tamper-evident holders with certification numbers.

Why buy graded coins?

Certification gives independent confirmation of condition and authenticity. It is most useful when grade, rarity, or presentation matters beyond bullion metal value.

How do I choose between PCGS and NGC?

Both services are widely recognised. Many collectors follow the service already on a coin, or compare population reports and recent sale prices for the same grade.

What does MS70 or PF70 mean?

MS70 and PF70 are top grades under Mint State and Proof scales, indicating a coin judged flawless under the grading standard. They usually carry a premium over lower grades and ungraded bullion.
