Lamination Flaw Coin Error: I like to think of this error as one where the thin layer of on top of the impurity metal from the coin has not really detached from the coin.
lamination: Coinage defect consisting of a portion of the metal separating from the rest due to impurities or internal stresses; common with clad or plated coinage.
Lamination Errors
All dimes, quarters and half dollars are currently minted on blanks cut from the prescribed clad strip that consists of outer layers of copper-nickel (75% copper and 25% nickel) bonded to an inner core of pure copper.
lamination A thin piece of metal that has nearly become detached from the surface of a coin. If this breaks off, an irregular hole or planchet flaw is left.
Lamination - A form of planchet flaw caused by imperfections in the metal, whereby a thin strip of the metal separates itself from the coin.

Cleaning, marks, rim dings, severe laminations and stains can effect the value in any given grade. Circulated coins with original surfaces are more valuable than those which have been subjected to harsh cleaning or mishandling.
Nickel is impractical for coin production, as its hardness is conducive to laminations, die breaks, poor strikes, and many other problems.
Sometimes bubbles, laminations, and streaks occur which can be transferred to coins.
Additionally on this example there is a lamination flaw at the ON. Possibly the line running from the first stroke of that N to the bust is another die crack rather than part of the lamination flaw.
This applies to planchet laminations, lint marks, die rust, die wear, or practically any other mint caused defect. (Note: Minor die scratches and clashed dies are not usually considered to be serious defects, and hardly affect the grade, if at all.
Some examples show laminations or other mint-made defects. Many coins of this date have clashmarks on both obverse and reverse.
planchet defects
Any of the various abnormalities found on coin blanks. These include drift marks, laminations, clips, and so forth.
planchet flaw
An irregular hole in a coin blank, sometimes the result of a lamination that has broken away.
1908 Liberty Nickel
This Liberty nickel has a large lamination on the lower reverse. This is a magnification of the left pellet in the center of the lamination.
Grade: VF but weak areas on the obverse, and a small lamination has come away on the shield below the crown.
Obverse: Eagle with wings spread, with WENCEL ROMANOR Z BOEM REX around.
Strip rolled from these ingots (and therefore also, in turn, the planchets cut from it) came out with too many cavities (pit marks) and laminations (flakes, cracks, and splits).
Fully struck with hardly a mark. The coin is a beautiful russet-toned example. The clash is strong and plainly visible. The only reason this is not a higher grade is a planchet lamination flaw under the neck of the Eagle. It is a MS64 otherwise.
