i was going through my change today, and was surprised to find this 1970 d Black Nickel. I have been trying to find more information on it, but can't seem to find anything about 1970 nickels being minted like this. It looks authentic and not painted. Coin is also in mint condition to my eyes, but I am not a collector of coins, so I wouldn't know much about the condition. Any info would be much appreciated.   |

it is a very cool and nice looking coin, first time I have ever seen one, and I work in retail so I see coins everyday, all day long. Seems like no one knows anything about this coin since I haven't received any remarks on it.. guess I will have to keep searching for more info.

I thought they were from primarily the 50's but I am seeing discussions that indicate differently. Coop posted this link in a previous thread: https://groups.google.com/forum/#!t.../0OTPm6OmPlE. In that thread Mike Diamond states: Quote:
I had a 1959 black beauty nickel subjected to a spectroscopic analysis. The surface was enriched in copper (83% vs. the normal 75%). The metallurgist who performed the test was puzzled about the black appearance. Black nickels are concentrated in the late 1950's and early 1960's, but occur throughout the last 50 years. Black dimes and quarters also occur. Some say it's a manifestation of "copper wash". This idea holds that planchets rinsed in a bath saturated with copper ions will turn various colors from copper to red to brown to black. Indeed, one can find coins in which the surface changes from red or copper to black. The problem with the copper wash hypothesis is that black, red, brown, and copper nickels, dimes, and quarters occur after 1982, when there is no obvious source of free copper ions. and then quantifies with: Quote:
I was only speaking of BU, mint-state coins. Once a coin gets out into an uncontrolled environment, it can turn almost any conceivable color, depending on the conditions it's subjected to. Mike Diamond is the go-to guy for errors and I take what he has written as gospel. Hope this helps.  EDIT: Edited by CoinsKelly

Is the rim the same color? Just wondering, and it is very cool looking.

The rim is the same color, but shinier in some spots. It also has fs under Jefferson.

eq0120, If you want to do some research look up:sintered planchet and improper annealed planchet and improper alloy mixture. I found one awhile back but mine is yellowish not black. https://goccf.com/t/136747John1 |

thanks for the link and advice john1, I was doing some research, and couldn't find to much info on the 1970 nickels. I did read that it occurs from the improper alloy mixtures, and it happens naturally over time, but I wasn't able to find a coin from 1970 anywhere online that was solid black like the coin I found.
I'm going to keep on researching, and might take it to a coin collector here in Michigan to see if I can get some more info on it.
