Copper Core Nickel (Pics now included) I found a jefferson nickel in circulation that has a copper core sandwiched between a silver metal (nickel?). Kinda like a quarter. It's not a nickel struck on a quarter planchet because it's the same exact size as a nickel. The copper core is thick enough that it is protruding through both the front and back of it.
Hi, This coin has reacted to something, possibly as a result of being buried. Nickels that corrode and are damaged like this one will often take on some unusual colors. You can see the green from corrosion on the coin and the damaged surfaces also indicationg that the coin was probably buried. Have Fun, Bill
I've seen many of coins that were affected by a chemical reaction and ground effects and this is definitely not one of them. Look again at the first pic showing the side of the coin. The green you're seeing is actually from my scanner. When I first scanned it, the pic came out in a purplish hue. I adjusted the hue the best I could but it's still showing it a little greenish. It's true colors are silver, black and copper. You've got to see this thing to appreciate it.
Sure looks like it was coined using the wrong planchet stock. Same thicknes as an ordinary nickel, is it?
It's definitely the same thickness as other nickels. I took this one and an ordinary nickel and layed them side by side on a flat surface. I slid another coin across the 2 to see if it would catch and it doen't. Here's some pics comparing it with a normal nickel.
Interesting puzzle you have given us Maybe defective planchet material, not mixed well enough. Maybe somebody copper plated it and threw it back into circulation, this happens a lot. The poor thing is so beat up that I doubt you could get anything more than face for it though. It just looks damaged But thanks so much for the pics and for sharing, I really enjoyed it
Hi, By looking at the condition of the coin, you can see that it has had a rough life after it left the mint. On occasion, the copper and nickel are not mixed well enough and you have what is called a "sintered" planchet. Some of the copper that is not mixed in well enough is visible. There is an outside chance that this is what it is. Still noth worth more than five cents. It is definitely not struck on a wrong planchet. After having looked at well over 500,000 circulated nickels in my lifetime, I still think it is just a corrosion of some sort that has dis-colored the coin. Have Fun, Bill
Sure looks like a wrong planchet material error to me. Looks exactly like it was struck on clad planchet material. I think you have a very nice find. Congratulations!
There is no clad material that could account for this. later when i have time to spare, i will scan a sintered planchet and post what it looks like here.
Hi All, This is a picture of a Jefferson Nickel struck on a sintered planchet. It is a result of the alloy not being mixed properly. On a coin that is in this condition, it can easily be attributed as a "sintered planchet error" . When a coin is pitted, damaged, worn and corroded, the likely suspect for any discoloration is corrosion of some sort. That will bring about many possibilities of color variations. Have Fun, Bill
I'll take your word for it Bill that the nickel is struck on a sintered planchet - thus the color. But a sintered planchet has nothing to do with the alloy mix. Sintered planchets occur during the annealing process.
Hi, Yes, Yes, yes! Sorry you are correct!! I don't know what I was thinking. See the following page and scroll down to sintered. http://search.netscape.com/ns/boomf.../hermes.csd.net/~coneca/content/glossary.html Thanks, Bill
Geeeez Bill, no reason to be sorry. Everybody makes a mistake now and then. Matter of fact, I do it so often that Roy even went so far as to go and find me my own little icon for those times - Kinda fittin aint it
Hi, LOL!! Thanks, I just feel lousy when i blow a brain PHBBBBT!! I don't like to post erroneous info. Have Fun, Bill
