{"title":"MS66 Graded Coins","description":"\u003cp\u003eMS66 Graded Coins are grouped by an assigned condition or production category, not by metal purity. Mint State grades describe uncirculated coins, which can still show contact marks from production and handling.\u003c\/p\u003e\u003ch2\u003eHow numeric coin grading developed\u003c\/h2\u003e\u003cp\u003eThe Sheldon scale began as a way to describe condition in early American copper cents and later became a broader numismatic reference. Modern third-party certification grew with PCGS in 1986 and NGC in 1987. NGC means Numismatic Guaranty Company; PCGS means Professional Coin Grading Service. Both are grading services, not the original issuing mint.\u003c\/p\u003e\u003ch2\u003eA grade is not a percentage of precious metal\u003c\/h2\u003e\u003cp\u003eThe number on a holder does not state gold or silver purity, issue size or mintage. MS, PF, PR and SP identify different production or condition categories. A date identifies the coin’s issue, while the certification number connects the holder with a grading record. These details belong together when describing a certified coin.\u003c\/p\u003e\u003ch2\u003eUnderstand the designation\u003c\/h2\u003e\u003cp\u003eMS66 is a Mint State designation in this category. Numeric coin grades use a 70 point scale, but the prefix identifies the grading category.

NGC commonly uses PF and PCGS commonly uses PR for proof designations.
