$10 Liberty Gold Coins MS 61
MS 61 is a contraction for the denotation of "Mint State Grade 61", a grade on the Sheldon Scale. The scale was invented by Dr. W. H. Sheldon in 1949. His original goal was to create a system to better categorize the condition of Large Cent coins, but his invention was adapted to grade all American coinage. "Mint State" means the coin is in "Uncirculated" condition, and this particular designation begins at MS 60.
Specifics of the Grade
A $10 Liberty gold piece in MS 61 condition will still carry some of it's original "Mint luster" or golden shine. "Mint luster" is created by the sheer force of the U.S. Mint presses, which physically liquifies the gold during the striking process. There will be visible areas where the shine has dissipated. Scuffs and nicks, or groups of scratches, may be visible on the prominent artwork of the coin, including the likeness of "Lady Liberty" wearing her coronet. There also may be visible raised hairline "Cracks", that are caused by small cracks in the dies transferring their negative images in the minting process. "Bag marks", or physical wear from being stored in the bottom of a bank bag of gold coins, are also not uncommon on a MS 61 $10 Liberty gold coin.
