probably for the same reason we say a coin "has a die chip" when in reality it's the die that has the chip

https://www.error-ref.com/part-v-planchet-errors/Quote:PART V. Planchet Errors: Lamination: Lamination Cracks Definition: Lamination errors are planchet errors in which the surface of a coin cracks and flakes. It is generally believed that lamination errors are caused by contaminants in the alloy that cause the metal to separate along the horizontal plane. Lamination errors can develop before or after the strike. They are generally restricted to solid-alloy coins. The term "lamination error" is grammatically incorrect as the metal is actually delaminating. While "delamination error" would be the proper term, we're stuck with the terminology we've inherited from previous researchers. Thanks, Doug.

From some years I try to teach collectors or forums user about terminology.
Lamination it is a process of put together two different materials by many kind of procedures.
1. The right terms for coins will be Delamination and Exfoliation. those two are different from point of view of physics, chemistry and material mechanics because is due to the linear forces applied to the materials.
2. Another it is the Cracked Planchet which is different because on this the molecular or crystalline separation is due to the vertical forces.
3. And third: Cracked planchet due to the oldness of the materials which it is a cause of the different environments constants.
Hope help you. Why the majority still use the old terms? Because to change an old behavior or language it is very hard to achieve. Hope the new generation of the collectors will learn the correct terminology. Ken, Will and Mike understood this, but hard to fight.
PS: lamination mean union
the rest of the terms describe here mean separation

It actually isn't that bad. Through our continued use of the term, it has become the name of this error. What these layers of coin metal are doing "IS" de-laminating , a verb .
Every time we see one we call it "A" Lamination,a noun.
We have given our little error it's name.
Even more,we use it shortened as a nickname ,a Lam .

@Stone: Maybe it is a nickname. OK, but this nickname has many aspects which is a big aspect for the values of the coin. A ex-foliation of the coin due to the age of the coin has almost no added value, but an ex-foliation due to the rolling is complete another game. The first is normal course of passing years and the second it is an error.
Please your thinks of this.

Maybe similar to why saying "husking an ear of corn" actually means to dehusk it. Or why peeling an orange means removing the peel.

husking an ear of corn What original was " husk ash of corn" (some where before 700 in Britannia) Your examples mean same, difference is old or modern expression. So it is same meaning in your expressions. On this topic we discuss expression which has no same meaning. :Lamination" is not and it is opposite to : "Delamination or Ex-Foliation" |

The error lexicon is riddled with a large number of grammatical atrocities.

Perhaps the numismatic universe needs to form a body made up of numismatic elites (nice term, no?). Purpose would be to convene meetings of 'the body' to tidy-up the numismatic lexicon. Meet across a full year at different locations, interacting with interested, passionate numismatists. Circulate the new lexicon for review. Make any adjustments and publish.
Or not...

I just presumed that the term meant that a lamination was created where there should not be one due to bad metal. I didn't think that a coin that was not intended to be laminated in the first place could be considered delaminated.
As in "What is wrong with this coin?" ans: "A laminate was created on the planchet during manufacturing"
