Lamination

Coins | Stan McDonald - author

Lamination is attributed to a defective planchet. Under pressure from the minting process, a part of the coin's surface peels away or breaks off. When the flaw stays on the coin, it is noted as "retained lamination."
The 1998 Lincoln cent in the photo has a small lamination on the portrait. The second photo shows a Lincoln cent with a patch of the surface peeling away. The third photo shows lamination that is retained on the coin. Retained lamination is rare since most of the laminations fall away from the surface of the coin.Stan McDonald - Author and NumismatistI hope these quick snapshots provide good information for collectors. I have close to one hundred of these compiled, all in my number one selling book that I will continue to share with collectors.I will reply to all questions.

Seen to many . Again I say you will find these on many coins. The mint does not care about quality when there making billions of coins. They just keep using the same dies. There is little quality control. They just don't care. And most of the third party graders dont either

Why do you say the Mint does not care? Who are third-party graders? In my opinion, there are no third-party graders, only us. We are the third-party graders, so if you go to a coin shop and they say, "this coin is MS65, I always say, "how do you know?" Iask, "What are your criteria? What makes you an expert? The true graders are the grading services and they catch 99.9 percent of all flaws. I use them all the time and get MS66 or higher (only because I might have enough experience to get coins with MS66 or higher to send to them. I can grade coins from MS60 to MS66, but higher than that I even get lost on business strikes Actually, the Mint does care about quality and workers reject thousands of coins. Most of the lamination errors are so small you need a 10x loop to see them. The majority of our coins are close to perfect. Hope this helps

Seen quite a few lamination issues on coins. Never paid much attention to them. Have a couple saved that I liked. So many interesting issues with coins. Perfect is hard to come by.

They can get to be looking real gnarly in the extreme cases
