1993 Experimental Lincoln cent?

It's possible that two plachets got stuck together when it was minted. That would explain the think rim and the crack in it. How are you identifying that they it is aluminum? You could try a density test.

looks like its copper plated zinc to me, u can see the plating defects in the pics..

 

Well, it is a bit lighter than a thin zinc. It appears to be polished well and copper aluminum makes the same sound when dropped; lightly that is. It closely resembles experimental cents and is a whitish copper. How do I try a density test? Never done it before

 

If it is a copper or bronze aluminum, that would explain the weight

 

The weight is the same then it has to be a regular coin. The density of zinc is 7.13 g/cm3 and the density of aluminum is 2.7 g/cm3 so the amount of aluminum would need to be 2.6 time larger, making the coin 2.6 times larger.

 

How do I test it?

 

You don't test it, those are what they are. You have a well struck cent, that's it.

 

ok; well, thanks for the information; I will have it checked out; I just dont see a business strike coming out this perfect with this color and characteristics; I mean, what are the odds of a business strike coming out to look like a proof and lighter than a zinc? I will close this discussion

 

First coin out of brand new dies? I see only copper color.

 

This coin can be a touchy subject; you truly would have to hold it

 

I feel like I've had to use this emoticon too much lately...

 

Its k if you dont believe me; Ill take it from here

 

yet another one for the "ignore" feature...

 

Mikey, did you ever make billions of anything? Billions of anything are going to push the tolerances. If this is truly out of tolerance, technically, it's an error. But, then, who cares?

 

not OP obviously...

 

ok, all done here. thanks

 

Take some wire snips and cut it in half.. lets see what's in the core! That's what I do!

 

Looks like they spelled CENT incorrectly. I mean, even though in the picture (nice and focused BTW - kudos) it "looks" like there is a C followed by an E followed by an N followed by a T, I think that is just the camera playing tricks. In reality, and I bet you can see this as you hold it in your very own hands, the C is a B. I bet it is the widely known BENT CENT from 1993 - an experimental coin of which only 2 are known to exist. Minted using a technique involving the bending of light around a black hole, sending it through a worm hole into the core of the sun where nude leprechauns polish the coin using their...

Well, suffice it to say that if I were you I would send it in to get certified. It's worth it.

 

I've noticed on DOLAR coins the L is doubled. Is that an error?
