how did this cent get this,or is it a mint error.
the half dollar has some numbers punch in to it 1960-1985

Can you say "post-mint damage"?

 

Why's that half counter-stamped like that? What type of anniversary would that have been?

EDIT:

Ah, saw Twiggs response. 25th anniversary! Should have thought of that.:desk:

 

Are you SURE the Lincoln is ?
I know the letters on the reverse look hammer-jobbed in, but wouldn't it be hard to do just in that small area ?

 

It looks like post mint damage to me. The weird thing is the letters "TRU" over AMERICA. It looks like someone hammered this coin over another one.

Yeah, that's what I was commenting about.
It's in a really small tight area.
You'd think there would be more marking than just that bit.
I suppose the imprinting coin could have been bent or merely a partial piece.

 

found this kennedy like yours but in gold

just found this on wiki answers

 

the half is gold , now the cent the word OF is almost gone, can you guys see the date i cant 19??

 

The cent has some interesting attributes, including the fattened rim, there are some better error experts that should look at this one. It just might be a mint process error, struck through cent fragments.

 

maybe

 

I've found chrome plated 1985 kennedies counterpunched just like OP's.

The cent has potential, but that is a tough one to explain. But let me try.

The obverse and reverse die broke due to an obstruction.

A piece of the oberse die became recessed.

A cent was stamped and the part of the die that was broke cut off a piece of a planchet and retained it in the reverse die.

The broken die (with the broken part of the die filled with a partial cent) continued on to stamp this coin thus leaving the mirror part of the obverse on the reverse.

You will notice that the missing date lines up with the image on the reverse where the missing part of the die would be. The broken piece of the die could cause the damage seen elsewhere on the obverse die.

=================

My theory requires more thought as to which dies broke missing pieces in which order to retain a piece of a cent, but one thing is clear, the mirror image on the reverse is raised. You cannot get that with a hammer job. Plain and simple, that was caused during the stamping process. The damage to the upper part of the obverse die could also have been caused by part of a broken collar die between the obverse die and the planchet.

 

wow then i could have a nice error,yes

 

Twiggs:
Starting bid: US $179.00

Buy It Now price: US $600.00

Looks like someone is doing very good drugs.

 

I didn't even notice the prices when I looked at it. Holy crap is all I can say. The funny part would be if someone actually paid it.

I also find it funny when companies feel the need to specify "24K Gold Plated". As if you could figure out how to electroplate a Gold Alloy.

 

Post mint damage, both coins.

The cent was on top of another cent when it was hit hard by something in the area of the date. This caused the TRUS of the underlying cent to be impressed into the word AMERICA. This was the only area impressed because the point of impact was very localized. Notice that the coin is distorted outward in that area, yet the coin show a full and well developed rim all the way around. This indicates that the cent was originally struck in the collar, but the damage outward in the date area and at AMERICA on the reverse means that that impact took place when the previously struck con was NOT in the collar. Hence post mint. Also note that the letters of TRUS are impressed into the coin but it is not a "Piece of a cent" impressed into it. On the other side something did get impressed into the date but it does not seem to be a piece of a coin or die.

And even if it was you would still have to have another cent on the other side to create the reversed TRUS. To have that all happen in the press you would have to have stacked in the press reverse die, blank planchet (for support and to make sure nothing mars the coin during the error strike), a broken piece of die, the coin in question obverse down, another previously struck cent also obverse down, and the obverse die. That is four pieces that have to get stacked up between the dies between strikes.

Of the two ways I've described about how it could be made the two cents, an object, and a hammer is much more likely.

The weak OF on the reverse is not unusual on Lincoln memorial cents. Get a handful of cents and you will probably find a few.

It can be done. Use an anode of the alloy you want to plate and a plating solution that contains both copper and gold ions in solution. As you plate both copper and gold atoms will come off the anode and the cathode will be plated with both as a solid electrically deposited alloy. You can also use two anodes, one of copper and one gold, and you can control the fineness of the deposited alloy by the strength of the voltage potentials between the anodes and the cathode. Same potential result is 12Kt. Increase the potential on the copper anode you get 10Kt (more coper deposited). Increase the gold anode potential get 14Kt.

(actually if the potentials are the same the fineness will be a little less than 12Kt because it takes a little more energy to remove a gold atom from the anode than a copper one, but you see the principle)

 

Twiggs- thanks for the link.

Over the years I've found probably 10-12 of the counter stamped Kennedy halves. The dates stamped into the coins varried, as did the dates of the coins themselves. Most were gold plated, a couple were just polished.

It was nice to see some accompanying documentation for a change.

 

I lightend up these photos some...maybe you all can see the error better now.

atrox,

I think that cent needs to be looked at by someone in person.

 

What I see more clearly is the accuracy of Conder101's comment about the reverse rim!

BTW Gatzdon - your theory utterly fails Occam's test.

 

You are definitely correct on that. The only thing that really calls my attention is that the area with the mirrored TRUST appears to be raised, but I know that scans don't actually tell the whole truth accurately, hence, I think OP needs to get the help of someone who can physically look at the coin. If the area is depressed instead of raised, then due to the rim, there is no doubt in my mind that it's post mint damage.
