Double stamp penny dates 10 years apart

Ok, I have a penny that appears to be double stamped at the mint. Curios fact is that the dates are 10 years apart. I cannot explain it other than an employees took a 1957 penny and ran it through the 1967 stamp. can anyone help me with this issue? I was told once that it was a fake but How can you duplicate it in this fashion with out access to the coin die?

The lettering and date would be backwards if it were a vise job. I'll go with false dies being used for the second strike.

 

I would agree with the vice job theory but the imprints are "Raised" not imprinted. I am not seeking an argument with anyone I am just trying to figure out what I have....

 

But the letters are not backwards as they would be with a squeeze like you are suggesting.

 

nvm,I'm just going to get back to that algebraic equation,my brain hurts!!.

 

@Idhair is onto something here. Not sure what caused this but something is hokey.

 

I am not your error guy, but am long studied in US coins. I cannot envision any sort of wild scenario that would allow this to play out inside the US mint..... However, having said that I cannot for the life of me fathom how somebody would create this in their garage short of building a die as suggested by @ldhair. Most certainly is an interesting oddball, but am confident this didn't depart the US mint like this.

 

Thanks all.....it is definitely an odd ball. Any suggestions as to value and authenticity are welcome. I have a few more errors but nothing like this...

 

False die seems to be the most likely but why? Why no others (if that is the case)? This is the only one I have ever seen or heard of but I am a novice coin guy.

 

I'm tagging @Fred Weinberg and hopefully he might shed some light on this. He would likely know.

 

If they are 10 years apart it happened outside of the mint, intentionally to trick someone into thinking it's some rare and valuable error. While not impossible (cough, cough) it's unlikely there are 10 year old coins laying around the mint, waiting to be struck again.
The 1957 was struck at Denver. The 1965,66 and 67 coins have no mintmarks, but were struck at all 3 mints.
It's certainly nice to have a copper cent with the memorial and wheat back,
but I don't see how this could be a legitimate coin error. If it was the same date, that type of error should be more likely than this.
I mean you could have a clandestine mint worker who tossed in a 1957-D into the planchet bin in 1967, but then there's no way to retrieve it. Since a one of a kind error like this could be worth a fortune, why allow it into circulation?

 

Thanks

 

It's called a false die. I've seen many like yours over the decades. They all look similar. Tilted added high relief image. Altered to look like an error.
How it's done? Only the tricksters that came up with the technique can tell you that.
@JCro57 Can tell us more about it.

I want to share the NGC website information of a similar Cent.

I inherited it so I have no idea about origin...

 

I think I know how it's done.
The Old " Coin between leather trick". Beat it with a hammer.

 

I almost dislike asking this question, but would one these have an extra value, or is it done so someone can say "I can".

 

Well the counterfeit Henning nickels are hundreds of dollars.In this instance yes I believe at least it has a little something extra for the nostalgic factor.
