$20 Liberty Gold Coins MS 63
MS 63 is the contraction for the denotation "Mint State Grade 63". The "Mint State" designation means the coin was uncirculated, and that designation begins at MS 60, and ends at MS 70, which is the very top of the "Sheldon Grading Scale" named for it's inventor, Dr. William Herbert Sheldon. Gold coins are soft however, and even though "Uncirculated", coins this old show wear, and $20 Liberty gold coins seldom grade above MS 66 or MS 67 no matter how perfect they may seem to the untrained and un-aided eye.
Specifics of the Grade
Uncirculated $20 Liberty gold coins in grade MS 63 are pleasing to the eye and generally have a fair amount of "Mint luster" or "Sheen" to them. Any scratches or scuffs will be smaller than those on MS 62or MS 61 coins, or they will be in less prominent areas. Flaws in the minting process may or will still be apparent, such as a light strike, but the flaws will be less pronounced or even undiscernible to the naked and untrained eye.
