Undated 2 Euro Struck With 2 Reverse Dies NGC AU-58

This is another piece of sculpture that was left to me from my grand father. I guess he was lucky. He even said to me once " the Pennache ". with those 777, will bring me luck one day" He meant by the 1977 in the observe and the one 7 on the reverse. sure enough he found this 4 Euro. No one believed him that it was genuine so I had it published to prove everyone otherwise. My Grandfather wanted to keep everything to himself and could careless of what people thought. I thought that I would clear things out for all of those pessimists.

Proves absolutely nothing.
That is not having it published.
That is no different than having someone else post it for you on this forum.

Too bad that Canadian cent is circulated... mint state it would be a nice coin at $600 or so... circulated, from the 1970s, it is worth about $200.

Hello. Does anyone know anyone know of any auctions or private buyers that would be interested in this 4 Euro? Please send email.

Eh, might as well be Wikipedia. Hardly classifies as an update.

Even your expert says it's implausible it's an unintended error, and you completely ignore that rather essential piece of information. If you think it's worth so much, bring it to auction. You'll find out in no time what the actual value is. I'm afraid though you'll be disappointed.

"To be or not to be"encapsulated? And that was the question when this coin was in the hands of NGC. Understanding the fact that with the Mint machine it is equally possible for an 2 eur to be struck on both side just like any other coins because The planchet already has both metals in it. We can then conclude and agree that NGC has encapsulated this coin understanding the fact that it is not impossible for such coin to genuinely exist. If NGC found in any way that this Mint error was impossible than we can all agree that this coin would not have been in an (1) NGC slab, (2)nor would NGC bother grading it or (3) register this coin in their book. I would like to Quote NGC practice moto.
"What coins will not be graded by NGC"

NGC will not grade coins that are counterfeit, are of questionable authenticity or have been altered. In addition, NGC will not grade coins that have active surface contaminants such as PVC residue. These coins will often be eligible for NGC certification after conservation by Numismatic Conservation Services (NCS), an independent affiliate of NGC.

Hence, the decision was already made and NGC has agreed for this coin to be everything but "counterfeit" or of a questionable authenticity or altered. Just like the "two tailed set" which was certified as genuine and slabbed by ANACS"

So please to all of those with question marks wondering if this coin is to themselves genuine or not. Wonder all you want but the final decision was already made by qualified NGC experts and that for me is a closed case.

As to what it may be worth. Well all depends on the numbers of individuals interested in this coin if this coin were to be submitted to an auction. On the other hand it could be only 1 individual , a private collector who could snatch this one at the best price offer.

If there was a US dime with a nail sold for $42,000 of which around 6 of it's kind exist(URS-4) and a "Two Tailed" set of U.S. three Quarters (URS-3) of which 1 of those 3
Quarters sold for $80,000,than I really don't see how could this one of a kind 4EURO be worth less than 6 digits.
Like other coins, the value of errors is based, in part at least, on rarity and condition. In general, lower denomination errors are less expensive than higher denomination errors simply more such coins are minted resulting in available errors.
Also we look at the other stats such :
URS-0 None known
URS-1 1 known, unique
URS-2 2 known
URS-3 3 or 4 known
URS-4 5 to 8 known
URS-5 9 to 16 known
URS-6 17 to 32 known
URS-7 33 to 64 known
URS-8 65 to 125 known
URS-9 126 to 250 known
URS-10 251 to 500 known
URS-11 501 to 1,000 known
URS-12 1,001 to 2,000 known
URS-13 2,001 to 4,000 known
URS-14 4,001 to 8,000 known
URS-15 8,001 to 16,000 known
URS-16 16,001 to 32,000 known
URS-17 32,001 to 65,000 known
URS-18 65,001 to 125,000 known
URS-19 125,001 to 250,000 known
URS-20 250,001 to 500,000 known

So is this URS-1 worth 6 digits? , well let's be honest here. Hm,

(1) this is the only known of it's kind to be certified as "genuine" , graded by NGC.
(2) this is the highest denomination out of the set of euros. There are 6 types of denomination from the EURO set. 1 Cent/ 5 Cent / 20 Cent /50 Cent /1 Euro and 2 Euro

and yes " qxy "member , I could be disappointed if I were to send this coin to an auction and find out that only 1 bidder was interested in the coin. It's not the first time that a coin was sent to an auction with an estimated value of so much and sold for so little because of lack of interest or demands but correct me if I'm wrong , this mostly happens with common Mint errors.

My Two Cents worth.

Hi there john100 and thank you for your input. However,I don't believe that there are many 1 euro double headed or tailed coins out there John. The last I heard was that there was 2 graded genuine and there are worth much more than the common 1 cent which fetched around $1600.00 USD back in the days. These 1 cents euro were shortly cut to half it's value after the quantities of them started to rise in the thousands. You can purchase the one 1 cent double headed or tail coins now these days for about $600.00 USD which is a nice count for a 1 cent. Good luck finding the 5 ,20 or 50 cent or 1 Euro but if you do then you could do the math as to what those may be worth.
John, I believe your were referring to the 1 Pound GBP and those are common just like many other GBP denomination and the GBP currency is also one of the most forged and counterfeit of it's kind but there are others to name a few : India , China. You could send all those GBP errors to NGC or any other respected grading co. and I bet you that 99.9% will never be slabbed. To me,A UK mint error is a red flag.
Like your input members and please if you can all; do add factual resources such as auction results info or recorded publishing material, all together with your remarks as it really makes a point then.
