$2.5 Liberty Gold Coins MS 63
MS 63 is the contraction for the denotation "Mint State Grade 63". The "Mint State" designation means the coin has not seen circulation among the general public for use as a currency, but more likely was held in bank vaults or even perhaps private hordes. The uncirculated "Mint State" grade begins at MS 60, and ends at MS 70, which is the very top of the "Sheldon Grading Scale". This scale was developed in 1949 by Dr. William Herbert Sheldon. The higher the MS grade, the higher the premium the coin will carry over the spot price of gold, and the rarer it will be.
Specifics of the Grade
Uncirculated $2 1/2 Liberty gold coins in grade MS 63 are quite pleasing to look at and own, and generally will still have a fair amount of golden shine or "Mint luster". Any scratches or scuffs will be smaller than those on MS 62 or MS 61 coins, or they will be in a less focal area, rather than on the main artwork of the coin. Due to the small size of the coin and the softness of the metal, any strong single blow could have damaged the coin resulting in a grade below Mint State, for this reason it is even less common for these coins to grade well.
