laminations on a coin, how evaluated?

krueger

For you minting process experts out there--
Do the laminations on a planchet occur before a strike. or occur during the strike?
When a coin has them do the TPGs ignore them for grading opinions , because they are of mint caused.
though not eye appealing for market grading . maybe should be considered an error piece?
I see differences in such opinions out there.

Here is the pcgs video on planchet flaws to answer some of the questions about what they accept (normally).
Planchet flaws starts about 40 seconds in and ends at about 2:20.

For modern coins, laminations can mint errors that add to the value. For early coins, like the 1793 Wreath Cent on the still part of the video, they lower the value no matter what grade the third party grader assigns to them.

The worst case I have seen was a 1793 C-4 half cent that Roger Cohen illustrated in his book. The sharpness of the piece was AU, but almost half of the obverse was gone from a huge lamination. Normally a 1793 Half Cent in AU would be worth well into 5 figures quite easily. When that one was auctioned, I think it only brought $3 or $4 thousand.

Laminations can happen after the coin has been struck also. Missing clad layers is basically a lamination where the whole layer of the coin came off.

Delamination's, whether retained or missing, are a personal dislike of mine. For some reason, I just do not like that issue with a coin. Like many things with coins, there are other collectors that like them. Much the same with art or literature. So, regarding value, for this collector, it is a complete pass. Cheers, RickO

Does anyone know how CAC treats laminations? I have a couple coins with small ones but otherwise very nice coins. Will they sticker?
