There's a good chance a few exist. They've got to be one in a billion, though.
As far as the post you're speaking of, that individual found a copper-plated cent that had overused copper plating in it. As the zinc planchets are dipped into the plating solution, a tiny bit of zinc is removed. Dip hundreds of thousands of planchets, and eventually the copper plating starts to turn golden-yellow... AKA "Brass" even though I'd debate the legitimacy of calling it brass.
AFAIK, they command no premium.
EDIT: Man, I'm making a TON of typo's today.

I'm with Merc on that,I'll bet Ricardocody's weigh 2.5 g...I've found about 5 of the 83's and though they look cool...no weight discrepency.I don't see any premium either...but I've been wrong before

I though copper and brass were 2 differenf metals but I heard in here that brass is just copper dipped in a solution that give it a yellow color looking to the planchet also changing the copper into brass ! So all the brass coins as presidential dollars*(*I think they are brass )marshal islands coins etc are just copper planchet dipped in a solution according to your text , m I correct ? this coin is a 10 dollar marshal islands made in brass from one of my sets so it is made in copper just dipped in the sotlution to give the copper this yellow gold kind of collo?  took more then 30 years to the US MINT recognize the 1943 copper War Nickel and I think one day they ll assume this planchet error as well because the us mint has been making copper and brass coins at the same time no secret but is just my opinion !

Brass is an alloy of copper and zinc.
Now US pennies are a zinc middle that is plated with pure copper outside(separate metals). The plating process however can form a solution of brass since you're dipping zinc into a copper bath solution. Some zinc from the blanks is lost into the dip tank, and over time the copper solution becomes a brass solution(copper/zinc solution). copper and zinc molecules together will plate the zinc core with what is technically brass instead of pure copper.

copper is an elemant "Cu" Zinc is an element "Zn" An alloy is mixture basically a mixture of two or more metals Brass is an alloy Brass: A yellowish alloy of copper and zinc, sometimes including small amounts of other metals, but usually 67 percent copper and 33 percent zinc. this is why I was confused about the post in question,  I hope I didn't offend anyone, it was not my intent

Oh, forgot to actually answer your question, no brass is not just dipped copper. Most brass alloys are around 70%copper/30% zinc(it varies) I have a hard time believe the dipping solutions reaching 30% zinc, but it reaches a small enough % to change the color of the plating from that of a pure copper tone to a weak brass tone.

As best as I can remember, I don't think anyone has found an 83 copper cent. A lot of us are looking for them, but zip.

Yes, the US Mint has acknowledged the existance of brass planchets at least as early as 1985. However, the US Mint has nothing to do with it. Since 1982, all zinc planchets have been supplied by an outside vendor- Jarden Zinc. They punch the blanks, mill the rims, and electroplate the planchets. The finished planchets are then shipped to the Mints for striking into Zincolns.

Ricardocody,the big thing we need is the weight..that would determine planchet or plating....big difference
