Buffalo Nickel question---help please

[jesbroken]

I've seen these streaks before, but do not know what causes them. Are they a natural occurence post mint, artificially incurred, or a minting or pre-minting issue. Just curious. Thanks for your help.

I believe what you have is planchet streaking caused by an improper mix of the alloy. I have seen it on a number of nickels, and is a part of the metal. There is nothing you can do about it. Some people like it, I understand, but I'm not a fan.

I thing you are right Physic-fan3.14

Not as prominent as yours Jim, but you get the drift.

These streaks arose from minor flaws in the mix of the raw ingot bars that composed of 75% Copper and 25% Nickel. Small concentrations of copper that did not have a chance to blend evenly with the much harder nickel were drawn out during the rolling process into the long coppery streaks that produce such “woodgrain” effect toning. Those are some nice examples.

 

 

 

Here’s a fancy name for the streaks, something like what James would describe:

 

“variegated amber patination”

improper alloy mix

 

extremely common

 

and with the age of the coin alongwith the toning the copper streaks become more pronunced

 

as the coin is 75% copper

[michael]

as nickel is a person_without_enough_empathy to properly alloy with any other metal

As far as the look goes I like it on some. It depends on the direction, severity and toning of the streaks. I like to think the buff on this one is standing against a blizzard and the Indian toned up with character.
