$10 Indian Head Gold Coins MS 64
MS 64 is the contraction for the denotation "Mint State Grade 64". This grade is part the Sheldon coin grading scale, which was created by Dr. William H. Sheldon in 1949. He was a Psychologist and numismatist, and he invented the scale to be applied to U.S. Large Cent coins, but his work was adapted to grade all U.S. coinage. Today PCGS and NGC, the two most reputable coin grading services in America, use his grading system.
Specifics of the Grade
A $10 Indian gold coin in MS 64 is often found to be quite pleasing to the eye, and any marks or scuffs will either be minute or in an area other than the Indian's main designs. Any defects created by the U.S. Mint, or the minting process itself, will probably not be visible to the un-aided eye, but will need a low power magnification and a trained eye to visualize. If a $10 Indian achieves a grade of MS 64, it's market value and desirability will increase because of it's condition, though the overall value of the coin will also be determined by the spot price of gold.
