1977-D Silver Half - Call Me Crazy!

I still think its clad. Just from the tone and color of the face

I had a 1980 I thought was strange it looked silver on the edges most the way around,
One spot about a inch showed the copper the rest all silver/nickle

It sounded funny like silver ring to it in the drop test being the copper was not correct in the center.

The coin was prob mostly nickle and the copper amount was not correct in the center making it ring like when you drop a nickle or a silver coin.

So it looked silver untill you got to one spot. Its called a clad lapse over strike meaning the nickle on both sides came over the copper or the copper was thin inside the center .

Sometimes when you look at quartes you see it one one side its all nickle and the copper shows on the other side

the 80 looked silverish
It was just nickle/clad that had a funny light brownish tone like silver gets.My suspect was it had been heated for some reason making the tone look like that of a silver 65-70 clad vs a reg clad
As I spun it arround some found a spot where the copper stuck out the side like a regular clad
I did the paper test.


Not many people talk about this test but it works
Its the paper mark test.
You can use silver coins like a pencil to write on paper it leaves a grey line, clad/ nickle does not leave the grey mark
Lay a piece of white paper on the table.
Take the coin sideways hold it like a pencil and press down rubbing the coin into the paper see what mark it leaves
The silver will leave a greyish mark like a pencil
the clad will not leave a mark.

Take a 40% silver draw a line
take a 90 silver draw a line
take a clad/nickle try and draw a line

then you will see exactly what I mean about leaving a pencil like grey mark and not leaving a grey mark

Look at your Photo 9 of 21. One "tell" that hasn't been mentioned is the luster grazes on the silvers which won't appear on the CUNIs. Another "tell" is the unmistakable pitch on a spin as the coin comes to rest.

I'm going to say it's a CUNI, just from the absence of the luster grazes.

I just read this entire post.....Im not going to say anything yet...except for maybe...does he know that "aluminum cent" guy?

Aluminum Cent guy and me are third cousins twice removed from my mothers sisters dogs friend and we will be having brunch tomorrow.

Do you have to specifically request that the coin be checked for "off metal", or will they just do it automatically?

It would be a shame for the coin to come back as a regular graded Kennedy and not be checked.

She thought that maybe it was an intentional mint error that may have been illegally released. Kind of similar to the aluminum penny, but mint error instead of intentional but experimental coin. She was just being sure because she had never heard of that particular error, instead of doing something and regretting it later.

Now I'm going through all my clad Halves just in case....

I didn't pay too much attention to mine when I was searching rolls. I would simply check the edge. If it was silver I would check the date. 1964 in one pile, anything with a silver edge not 1964 in another pile, everything else that wasn't exceptional AU in the spend pile.

I hope to see a definitive outcome posted on this thread. Either way it goes it is fun, informative, and exciting.

Out of curiosity, if it does turn out this is a clad 77' half, what could it possibly worth from a numanistic standpoint?
