Coins are sometimes flawed as made. NGC, as a general rule, will not assign numeric grades to coins having minor flaws such as rim clips or laminations. Major mint errors such as off-centered coins and wrong planchets are graded under NGC’s regular tiers as “Mint Error” coins.
PLANCHET FLAW describes a void or lamination (separation) in a coin’s planchet as made. OBV PLANCHET FLAW and REV PLANCHET FLAW provide a guide to the problem’s location.
CLIPPED PLANCHET refers to a portion missing from the edge of a coin’s planchet. A large missing area is gradeable as a Mint Error, while very small clips will result in Details Grading only.
As a general rule, NGC will not assign numeric grades to coins with minor flaws such as rim clips or, in this case, lamination.
