I'd like to see one in hand if anyone is up for that, I'll make sure you get it back. I'd just like to define once and for all if this is a plating or die issue.

Hi there again. Ugly, I have a few of those floating around here somewhere (not literally) and would be glad to send one for your use. Feel free to contact me.

@Ugly That's great that you're willing to offer your time and skill to determine what this is, and staircase for offering up one of your coins for review.

Staircase sent me a nickel and I have looked it over in detail. It is just a tad light, it has the "odd strike" noted in the thread throughout and it has a strange finish, heavily cartwheeled and a lack of mirror finishing on the planchet almost as if the die were not polished. Much more obvious on the reverse, but true on the obverse as well.
Where the coin is giving up it's secrets is on the third face, it's starting to peel and underneath the nickel layer is... another layer of nickel. It SHOULD be a layer of copper. This coin and I believe that coins like it are missing their copper plating step and have been directly nickel plated over their nickel flash coat and have potentially missed their cleaning bath as well (I suspect this to be true or it wouldn't be peeling, nickel sticks to nickel VERY well).
The copper plating is what's mostly responsible for the final shiny finishing of the five cent piece and other coins. It's also responsible for adding a layer of softness for the strike to take hold. You can polish a die all day but if the planchet is rough it's going to give up a sort of frosted finish and have huge cartwheel luster because there's only a very thin layer of nickel to move around.
Thank you to Staircase for handing over this sample... it's one of those instances where everything is so obvious once seen in hand.

A few days ago another coin similar to these popped up only its a 1998. After seeing it with both sides frosted your conclusions became my suspicions. Still am kind of thrilled to have another one from an earlier date, what can I say I like frosting on my cake too. Nice to know its not just some chemical coating (ie. old yogurt).
Thank you very much for your analysis Ugly.

Wait a minute there Roger. The 1998 nickel is cupro nickel alloy, not plated, this one I diagnosed is 2001p.
Would be an entirely different reason.

Nope that was a mistake on my part the new one is a 2001 P not a 1998.

Thanks Ugly for your analysis, glad the coin was useful. Your summary helps explain why those nickels have stood up so well after ten or so years of circulation.
