NGC gold coins are graded on the 70-point Sheldon scale. The highest grade (70) is assigned to
only those gold coins having no detectable post-production markings when magnified five times.
MS, or Mint State, gold coins are uncirculated and fall between 60 and 70 on the scale. MS grade
coins are most commonly considered to be of investment grade.
Most gold coins were struck in numerous varieties. NGC defines a variety as “a coin that differs
from its basic design type in some distinctive way and is thus differentiated by collectors.”
Due to their lengthy mintages, Liberty Head gold coins have the greatest number of varieties:
148, 217, 186, and 150 for MS Quarter Eagles, Half Eagles, Eagles, and Double Eagles
respectively. St. Gaudens Double Eagles, which are generally regarded as the premier gold coin
investment, have 52 MS variations.
The vast array of available types and varieties of NGC gold coins may seem overwhelming, but
a call to the gold coin experts at the Certified Gold Exchange is all you need to make the best
possible selection for your particular investment needs.
