1868 Experimental Aluminum Proof Set

Actually the Hall Process. Bessemer was a method of processing iron ore.

Also, not to make another post, aluminum tones so badly and is so soft, I can see slabbing these just to protect them...hmmm, wonder what THAT slabbing fee was?

What the heck is that one 4 from left on the top.

 

Man your all over that quick

 

protect them from what? wear or dings from handling?

Because we all know that the slabs won't stop toning.

 

You got that right!!

 

Aluminum doesn't seem to tone-up very well...

 

Fascinating thread. Anyone have another. Love this stuff. Almost as good as when you characters learned me about that stone mountain fitty center. Great stuff. And paddyman. You did good. Thanks all.

 

$3 gold minted from 1854-1889 "aluminum style"!

 

Yikes. Guess i got to hit the red book. Thanks

 

Yes to all of the above

"Because we all know that the slabs won't stop toning." No, but it slows it down.

 

the older I get the more I forget. Thank you for the correction.

 

It took me a couple of minutes to notice it...sounds right.

 

That's one fantastic set! If it were mine I'd seek out a professional coin conservationist and see if it could be placed, as is, in an environmentally safe holder where the coins could be viewed in their presentation case. I have nothing against TPG holders as many of my coins are in their holders. IMHO I would prefer the coins to be seen in the original case. (To each his own).

 

I'd like a closer look.

Would you send it to me for a look-see?

 

That's just the type of thing boiler78 would own. I think he posted images once but I can't find the thread. The guys collection is crazy.

 

I know nothing about this, but find it interesting that every shield on every coin shows darker toning than the adjacent areas - any explanation?

 

As others have said, aluminum doesn't tone well but I don't have the answer to your question. Have you looked at other BU shield coins if they tone the same?

 

They don't. It is a trick your eyes are playing on you. Since the shield areas are surrounded by lighter devices the fields in the shields LOOK dark. Trying to compare a surrounded dark area with a non-surrounded one of the same color will cause you to see the surrouned one as being darker.

 

Wow. If I won the lottery, that would be one of the items I would put on the list to buy. But only a set with the original velvet display box/card.
