What is the World's rarest coin?

The US 1849 $20 is unique. What's more, it's in the Smithsonian, so it will remain unavailable at any price.

But there are coins more rare than "unique - population one"...

There are many coins whose existence is only rumored. Some were known to exist at one time, but their whereabouts are unknown. There are several US pattern coins and California Fractionals which were considered unique at one time and cannot be located.

One example : 1869 5c J-690, whose existence is unconfirmed.*

Also J-640 and J-643.






* I think it has a bust of sasquatch instead of Liberty. But at least it's a female sasquatch. :bigeyes:

Actually, there are more than 11 of them. There are at least 2 in the Smithsonian. There is also a widely held belief that the coin that was sold for $7M was not the actual King Farouk specimen and his is still out there. And there have been rumors of some private collections owning one of these coins.

I've heard some well respected people quote 20-24 as the likely number of examples in existence, yet not necessarily public knowledge of their existence.

 

How about the upside down Jenny

 

All 'unique' coins are rarest coins.

 

Gold 20-stater of Eucratides, the largest gold coin ever minted in Antiquity. The coin weighs 169.2 grams, and has a diameter of 58 millimeters.

I believe there is only one known example that sits in the Bibliotheque Nationale in Paris

A good read on the history of the coin is here

 

Nice - you should do a Coin Exhibit on that piece. We'll add it to the museum.

I think a coin of which only one specimen from a ruler who issued no other coins trumps something with a different date. Like the antoninianus of Silbannicus or, up until a few years ago, the antoninianus of Domitian II (thankfully a second specimen was found in a stratified hoard, proving the authenticity of the first!).

 

I told you to give up on the stratified hoards that patrol the streets of Roma. You just don't listen.

I would have to say that the rarest coin in the world is a 2044 Canadian silver dollar. Since they do not exist, the only way to get one is for someone to travel back in time and sell one of them. In that case it would be the rarest coin to date.

If that is inplausable, I would vote the 1911 Canadian lead dollar with a population of 1.

 

Pop is 2 there is one in GB and one in Canada

 

Coin Exhibit? Museum? Where on the site do I find those?

 

below my post....

 

No Errors or Varieties Just NORMAL COIN
Mintage: YES but NOT UNIQUE COINS or PATTERS, Many people said 1913 V Liberty Nickels, I think that coin is pattern coin! It's not considered a business strike as long as it has never been circulated.
I'm talking about rarity of circulated coins.
It can be a coin with lot of MINTAGE, but how many of them are left today?How many examples? or maybe a coin with low mintage can also be more common than a coin with much more mintage.
I'm talking about coins that been lost IN CIRCULATION!
or they have very low number of known examples,so they are rare.

PRICE: NO
CONDITION: ANY
DESIRABLE: EVERYBODY LIKES TO COLLECT DIFFERENT COINS...

 

The 1911 Lead dollar has a population of 1, and the 1911 Silver dollar has a population of two. I was lucky enough to see both at the RCNA convention in Ottawa last summer.

 

I never knew there was one that was made of lead , I though it was only minted in silver. you learn something everyday.

 

The South African "Single 9" is by far the rarest coin in the world, with a official government mintage of only one coin in 1899. Coin is said to break the record for the most expensive coin in the world, valued at between $15-$50 million.

I think I am missing something

A regular coin of that type has both sides inscriptions and details in relief.

The Guinness Book Of Records states that there are many coins with only

one example. I saw some listed in Krause , but I do not remember them.

Some other rarest coins that listed in Krause are :

Egypt - 20 Qirsh / Piastres 1920 - 2 Pieces

Netherlands - 5 Guilder 1987 - 2 pieces.

Romania - 5 Lei with the portrait of Mihai Viteazul , 1992 (?) - 3 pieces

United States - 5 cents 1913 - 5 pieces

Israel - 50 lirot PROOF , year 1962 , similar to KM 40 , without "MEM" - 10 pieces

Israel - 100 lirot PROOF , year 1962 , similar to KM 41 , without "MEM" - 10 pieces

 

The Worlds Rarest Coin

This one: Hessen 2 Gulden 1848.

Last seen at auction in 1892. No other auction appearances in 120 years. Only example ever recorded, now in my collection. Is that rare??
