I understand sintering involves over-heating the planchets before pressing, but does it darken the whole thickness or just the surface? Like if you took a black beauty nickel and carved a divot out, would it be dark like the surface, or the normal nickel lighter gray?

That's a big question. Do you have one you are willing to sacrifice to find out?

It depends on what you think the reason is for the color. I believe it is an alloy problem, so the color should be uniform throughout. External explanations like sintering don't lend themselves to that.

I know that artificially darkened nickels are black, because they have been heated. If you take a divot out of the surface of one of these, the metal underneath is perfectly white.
I know.
I have fooled around with deliberately blackening copper nickel coins (Australian 20 Cents coins) on a kitchen stove.

Wow great question . While I have never cut one in half I have to say yes they would be the same color Greyish Black cobalt as the face of the coin because of a wrong alloy mix.

Black beauties are nothing more than environmental damage 99.9% of the time. Usually from heat.

Whoever started the myth that they are special should eat a few dozen.

I tried eating a few, all I did was spit out 1922 "Plain" Lincolns. Nothing special.

I could put up some argument with you on your comment but I'll reframe myself because I know that they surely do exist . Why are there so many 1959-P Jefferson nickels dark in color and rumor has it that there are a couple of more dated Nickels that claim to be BB's . Are you saying that a bunch of guys had a crazy idea to heat up only 1959-P Nickels .WOW ,that is a mind blower because every BB that I ever commented on or came across had the exact same characteristics ( color, Hue, and texture ). Hmm , Now for the Grand finally : How is it that I was able to obtain 3 or 4 rolls of 1959-P dark grey/ black cobalt Jefferson nickels back In 1961 & 1962 . I'm just not able to take photos of them ,they've also been buried in a crawl space for the last 58 years . Those of you who know me know that I'm not a BS'er ! Sorry Mox but I'm just expressing what I believe to be the truth behind genuine BB's . I am in NO way saying that fake heat treated Nickels are not out there ,of cause they are .

No offense taken, T-Bop

If you could demonstrate that the coloration was more than skin deep I would happily apologize for my incorrect opinion.

But I've cut more than a few, including the more gun metal gray of many 1959, and every one, without fail, is normal nickel color inside.

If that remains true, that the discoloration is only surface deep, then something must have happened AFTER the coin was minted.

I'm sure you don't believe that the mint added a layer on the exterior of the planchet which discolored in that way.

So show me a cut black beauty that's black inside and I will happily acknowledge that I've learned something new.

For now we'll let the mystery lie undisputed by both of us until scientific evidence can be established . For now this is still an open case , Agree my friend ?

Sorry to take so long to reply T-Bop, but of course.

We have way more fun disagreeing with one another
