I guess I can say that my coin dealer knows me pretty good. I have been going to him for over ten years so there is that. I went in the other day to make a payment and see if anything is new. Instead of pointing me to his stock he pulled out two coins he had set aside for me. I don't collect a lot of errors but I will purchase ones that catch my eye, or in this case my dealer's eye. They are a 1961 Lincoln cent with a Strike Over and an 1876 Nickel Three Cent with a lamination error. This blog is about the lamination error.
A lamination error is a type of planchet error in which the surface of the coin cracks and or flakes and can even break off. It is believed that this type of error is caused by contaminants in the alloy causing the metal to separate along, usually, a horizontal plane. It should be noted that the proper term for this is "delamination error" but that term is seldom used.
The nickel three cent coin was produced from 1865-1889. It was mainly minted because its cousin, the silver three cent piece or Trime, was being hoarded by the public. I won't go further into the physical aspects of the coin as this blog is about the error.
My specimen of this series appears to have been pretty well circulated so no one seems to have too worried about the surface error. Good for me. The obverse of my coin has quite a noticeable crack across it. I am going to call this a lamination error. It starts at about four o'clock on my coin, below the legend "AMERICA". The metal actually is lifting up the surface of the coin including some of the legend and traveling through and under Miss Liberty's hair and half way up her neck.
The metal in the crack is lifted all the way from the rest of the surface. It is as if there are two or three separate surfaces. Besides this, Liberty's cheek has a bubble like affect on it. It appears that there is a gap in the metal below the surface, lifting it up and waiting to "pop" and pull away. To finish of the outstanding feature of my error coin, another possible delamination of the metal mix starts at the top edge of the coin at 1 o'clock. It travels through the "O" and "F" in the legend "OF" and continuing into Liberty's hair. After short distance the crack becomes more like a scratch and goes the rest of the way down her hair.
Surprising, to me, there does not appear to be any planchet lamination errors on the reverse. I hope you enjoy this blog and learn from it. I am a relative newbie to error collecting even though I have been picking them up for years and I am learning as research. I find them interesting and very obtainable on average. Please check out the photos as well. Thanks!
