Check This Amazing 2000 5-Cent Error Out!!

That is one beautiful error SPP.

I am going to come from 'left field'.
There is a tiny kernel of skepticism in my mind.
I only feel about 95% happy with this piece.
It is that other nagging 5% that I am going to discuss here.

I would like to see a published opinion from the Mint on this piece. That is probably not available at this stage.
Until that happens, the 5% doubt remains.
It is for this reason that I would have no interest in this coin at auction, and I would feel obliged to warn others on a personal basis, what my grounds for doubt are.

I feel that there is a possibility that this may be a high quality 'shed job'.
Charles M.Larson in his book Numismatic Forgery,
shows how such a piece can be manufactured, with home made and hardened hubbed dies.

What led me to this thought is the fact that the 'reverse' of this double reverse error looks like to be the product of a 2nd generation hubbed die copy. The original for this could have been a well struck coin. Individual dies and hubs are normally re worked by the Mint, before being put to work. It seems that didn't happen in this case.

Genuine blanks can be obtained to facilitate such a 'shed job'.

Coins such as this one cannot be critically examined inside a slab, irrespective of the fact that the slab itself is genuine or not.

Not going to happen!

I would reason that although rarely, a dud coin in theory, could pass examination by a TPG.
It would need to be very good. Some duds have even passed muster under examination by leading auctioneers and dealers. That is why leading auctioneers cover their butts by offering unconditional guarantees. Usually such items are withdrawn from sale, prior to auction because someone might have raised doubt, even if at a later time, the suppect piece has later proven to be genuine.

Optimistically, I am 95% sure that this piece is genuine.
Pessimistically, I am 5% sure that it isn't.

That is why I think a professional investigation would be required. There could be a lot of money involved in this case.

I wouldn't want this group sitting on a jury :-).

Why people automatically jump to its a back door job or a fake is beyond me .

The mint is just a factory that produces a high volume of goods . Stop holding it up to standards that no factory can meet . Mistakes happen and they will continue to happen . There is nothing to say that the die shafts that are suppose to be machined different were not accidentally ground wrong . All it would take is a reverse die improperly set in with the obverse dies and machined along with them .

I think it does the person owning the coin a great disservice to have his item flamed so much without any evidence at all that it came about by improper means .

"All it would take is a reverse die improperly set in with the obverse dies and machined along with them."

I agree with that statement but there is something missing in it.... All it would take is a new reverse die and a slightly machined used die and a mint worker who doesn't realize that there are two reverse dies because its his/her first day on the job and they haven't been trained properly and they forgot their meds at home which prevents them from seeing double hence the reason for placing the second reverse die into its position.
Its not possible IMO

It appears nobody has asked the seller what he knows about the coin or the story behind it.

The seller states - " Most coin with 2 of the same side are Obverse, two reverse are the rarest and most are cents."
I havent seen a coin yet so far with two obverse's except trick coins. I did see a vid on how to make this exact coin and it would be nearly impossible to tell that its not real.
