I was just wondering which modern circulating coin that was produced for multiple years has the highest numista rarity index number, and just to start it I am throwing out the 2 and a half guilden coin from the Netherland Antilles, produced from 1989 to 2013 with a rarity number of 56. Can you find a higher number?
The Numista rarity index is wrongly termed. The rarity relates to how many members have the coin. Not to how rare it is in general. Off hand I don't have an example but there are coins on here with mintages in the low thousands that score in the 50's
Ideally it should be changed to Numista popularity index.

Hi Mark, I don't think the question is about the rareness of the coins but as it is questioned.
The Gibraltar 2005 £2 coin celebrating the battle of Trafalgar has a rating of 77,
produced until 2011 with each year after 2005 having a rating of 60.
That's the best I can find in my coins at the moment.
I deny nothing but doubt everything, opinions are made to be changed, how else is the truth to be gotten at.
When you enter a coin which does not exist in the Numista database, it will automatically start off with a rarity score of 100 no matter how rare the coin is or isn't.
So if you get a new 2017 coin before anyone else, it would get a score of 100.
I translate through Yandex. All languages are welcome.
I've seen it at 100, but that seems very temporary.
There is a token which I entered in the database (and am the sole owner on this site) and it has a rating of 97, indeed.

In my experience, the actual rare and valuable stuff has ratings in the 60s, 70s and 80s - if it has a rating in the 90s chances are it probably isn't so much valuable as uncommon and obscure. The really rare stuff, especially the gold, has ratings of 100, which means it's entered in the catalog for the chance someone has those but nobody claimed to actually have one so far. (And the really obscure stuff, such as my Bohemian 1/4 kreuzer, isn't in the catalog at all because nobody thought to include them... I actually recently bought a 17th century European coin that isn't even in Krause - it's that obscure).
I have, I think, less than a dozen pieces with ratings in the 90s; most of them are tokens, a few are random obscure coins from German states and the like (can't recall if all are German - some might be French or Austrian).
It's still not there, I checked (again). In fact, as far as I could tell, there's no 1/4 kreuzer from Bohemia listed at all.
It's supposed to be KM#280, I believe, and I didn't add it because the Krause catalog says it's silver, and my example is clearly copper, but for all I knew it was just really low quality billon and my example got the wrong patina. Or it could have been a contemporary counterfeit and copper for that reason, in which case I shouldn't add it at all (at least, not as my coin).
And for several years after buying it, I couldn't find any other examples anywhere online (all the searches only gave me my coin and the inconclusive drawing in Krause), so I had no idea what it was really supposed to look like (though I suspected from the denomination that it couldn't have been very good silver anyway).
On a hunch, I looked for it again just now, and did end up finding other examples (finally), and they're even more obviously copper. So at least now I know it's probably not a contemporary counterfeit; maybe I'll try to add it later.
Quote: "Cerulean"Instead of the rarity index, I would much rather know how many users own the coin. A simple tally would suffice.
I'd rather have both, personally - it's not very useful to know that 769 users or whatever own this coin type if you don't know how much (or little) this is, while "rarity index 13" is a lot more clear - it's an uncommon coin but not particularly scarce either.
OTOH, the tally is much easier to adjust for individual years; I've been trying to figure out the relative rarity of different years by looking at the length of the "want to exchange" lists, but past rarity 30-ish those lists often shrink down to a dozen people or less anyway.

I was thinking something along these lines as well - knowing 769 users have this coin doesn't mean a lot unless you know how many users there are on the site at the time of the counting (i.e. if there are 780 users, you can tell its extremely common, but if there are tens or hundreds of thousands of users, its not really that common). Seems like rarity index is doing an opposite of proportion of users with the coin: if only 2% of people have the coin, the rarity index is close to 98, whereas if 98% of people have the coin, it has a rarity index close to 2?
Here is a little graph of the NRI related to the number of owners ... not completely accurate but I had only a limited number of coins to work with (coins with only one year line).

Great graph!! Out of curiosity - where did you find how many people own the coin?
Referees have access to information about how many people own coins from their country. For example, I am one of the referees for New Zealand and when I click on the George VI halfpenny I get this information

i posted a new coin in numista and it start with a ranking of 97.
Sorry no Swaps. Paraguay Post Office is to risky and they don't allow to send coins nor notes

Right, when a page is created and nobody has entered the coin it has a rank of 100. Once you enter your own coin, it will go to 97.

Why this information is not public? I bet everyone would love to know those stats.

Agree, will be great to have stats

I asked this question 1-2 years ago and I didn't get any reasonable answer.
Probably because the information is so worthless. As one of the US referees, I can see the same type of information for US coins. You wouldn't believe the number of people who claim to have extremely rare and valuable coins.

Maybe the US - or any other country with good local catalogs and lots of local coin collectors - is not a good example. But for many countries there are lots of years of issue in catalogs that never existed in reality. And if nobody, or only 1-2 Numista members claim to have a specific year of issue, there's a possibility that this year of issue never existed.
It would be better to have an image for each year of issue of each coin. But even the number of collectors claiming to have each year of issue may be very helpful.

1804 Silver Dollar, Class I. This coin is often called the “King of U.S. Coins,” and for good reason—there are only fifteen known specimens of this silver coin in the world.
