$5 Liberty Gold Coins MS 62
MS 62 is the contraction for the denotation "Mint State Grade 62". "62" is a grade on the Sheldon coin grading scale. This scale was developed by Dr. W. H. Sheldon in 1949. Coins that have not been circulated are graded "60". Coins that are visually perfect in every way earn are graded "70", which is the top of the Sheldon scale. Old gold coins in lower denominations such as $5 did see heavy use in commerce, and therefore are seldom ever seen in a MS 70 grade. The finest specimens of $5 Liberty gold coins usually top out on the scale at a MS 65 or MS 66.
Specifics of the Grade
A $5 Liberty gold piece in MS 62 will show normal wear in the form of scuffs or scratches, and these marks will probably be in the more ornate and raised areas of the coin, such as the "Lady Liberty" or shielded eagle artwork. The MS 62 grade might also be given to a coin which has only a few scars from storage and transport over the decades, but exhibits several small flaws from it's original minting.
