copper with carbon spots

As with any naturally occurring defect on a coin, the affect on the grade is directly proportional to the size and number of the defect. A number of spots on a lower grade or average grade coin is perfectly acceptable. Higher grade coins (i.e 64, 65 and up) are allowed a few small spots and coins above 66 are seldom allowed to have any spotting. If the spots are much larger they can be construed as Corrosion or Environmental Damage and may keep the coin from being graded by NGC at all. In most cases carbon spots will lower the final grade to some degree even if it is only by a fraction of a grade.
