Taking a break from swapping for a while, but still interested in pre 1799 Spanish coins, I will make time for that!

Between those 2 the Lincoln Penny is a clear winner. The total QEII 3rd Portrait Pennies minted is less than most of the years of the Lincoln Penny.

I am sure that the German Federal Republic - 10 pfennig coin is the least wanted on Numista!
Even the French franc has a rarity of 5, which seems like the bottom - but the 10 pfennig has a rarity of 4, which I have never seen on any other coin.

Because the rarity is shown for type - not for year or mintmark, I don't take too much notice of it.
I only have few 10 pfennigs, I collect mintmark and year too, so loads to want in there.
I haven't seen any with less than 4 either. So far the winner is 10 pfennig.

I'd like to know how Numista rarity index is calculated !!!
Coin with no Numista owners : 100
Coin with 1 Numista owner : 97
German 10pf : I think almost every Numista member has it (20,000+ ?) : 4
World coins by date and mint place, 1850-2000

I am sure it is not. It is because a lot of people collect them by year and mint mark and that is why they want that coin. I've never seen that someone wanted 5, 10 or 20 centimes from my list.

I know that it goes like this:
Coin with no Numista owners : 100
Coin with 1 Numista owner : 97
Coin with 2 Numista owners: 95
Coin with 3 Numista owners: 93
Coin with 4 Numista owners: 92
That is as far as I know.

I have a German 5pf but not 10pf. So, no, not everyone on Numista has it. (My father doesn't either and he has an account here.)

That does make a lot of sense. Also, I sold my 1 Franc without a problem, and my 1/2 Franc will be sold when the auction ends (think it has a few days left).

Don't bother selling French new francs, just slip them into any vending machine for 25 cents.

Now, why do that when I can get way more than 25 cents for them on eBay? I certainly did on the 1 Franc... and I think the bid is 35 or 40 cents on the half Franc.

I would never sell low value coins like that individually because of the way the charges are worked out on our local online auction site.
I think the fee is 5% with a minimum of 50c. So if you sell something for 50c, by the time you've paid the commission you end up with no money at all, unless you add the commission onto your postage charges.

I think any of the ones with an index of "3" are the most common, as I don't think there are any 2's or 1's.

All the obvious suspects seem to be 3's: US lincoln cent, French pre-euro coins, UK pennies, ... so probably no 2's (yet?)
I anybody still wants any of these ... I have a good deal for you: €5 /kg
Still more people need to have them to get the rarity index further down

The coin in most collections is the French Franc and has a rarity index of 3.

Since the rarity index drops from 100 to 97 for one person, it stands to reason a rarity of less than 3 is not possible.
I have none of the Lincoln cents listed above listed because I don't bother to collect US dates after the end of silver.

They started minting a billion of these each year (in 1964 & 1965). Then eased off into the 1/4 to 1/2 billions until 1970's (& again in the 80's) so they got to be a contender for one of
the most common coins:

I am guessing that the only reason the coins noted so far (US cent, Japanese 1 yen, German Pfennig, etc.) are not 1's is because there are some new members that haven't entered all their coins yet and probably a few older members that only collect ancient's (Greek/Romian) or have some other specialty that does not include very common, low value, modern coins.

Check this out ElectronJohn. It is impossible to have a rarity of less than 3.

Yes I just figured that out today. One of my coins had a rarity of 100 until I entered it into the database. Then a day later it turned into a 97. So I figured that the scale for that index uses went by 3's (3, 6, 9, 12...). But that turns out to not be true since there are coins with rarity index numbers not evenly divisible by 3, like 8 and 14. Although it does seem that the two ends of the spectrum (0 and 100) jump by 3, skipping 1 and 2 or 99 and 98 for some reason.
But I think it might be possible to have a rarity index of 0 if every member of this site had a certain coin. That of course is unlikely to happen but if it did then I suspect all it would take would be for one member to remove it from his/her list and then the rarity index for that coin would jump to 3, skipping 1 and 2. Just a guess on my part though.

The end (0 or 1) is either infinity or if it's variable all members but because nearly half of Numistas accounts are empty I think it's infinity.

I have seen your graph on another thread I think. It is very cool. I would extrapolate that a coin with a 3 rarity index is owned by 1000 to 1200 members.

Because of the lack of data points at the end it's hard to extrapolate but I think it's more in the 10,000s.
Xavier is the only one who has the exact formula and the real answer.

Quote: "ElectronJohn"I would extrapolate that a coin with a 3 rarity index is owned by 1000 to 1200 members.
It will be much more, as
Idolenz says, probably in the 10,000s. The least index I have for a coin from a country where I'm referee of is 5. And that coin is owned by about 11,000 members. An index of 4 and 3 probably doubles and quadruples this number.
But of course the total amount of "members" which defines the rating number is an addition of the amount of members for each year line of that type. A date collector will own multiple year lines. For instance the Germany - Federal Republic 1 Mark coin (
https://en.numista.com/catalogue/pieces846.html), with an NRI index of 3, has 209 year lines (without the proofs!). A decent date collector can easily own 200 year lines, so it's very difficult to tell how many
different members own a certain coin type, maybe even Xavier doesn't know that.

I was researching some French coins tonight, and happened to notice that the
French 1 franc coin has a Numista Rarity index of
2. I'm not sure if this changed recently, as the lowest I remember seeing for any coin previously was 3.

Yeah, I believe 3 was the lowest earlier, but 2, that's impressive.
I got curious and checked a coin from a country I'm a referee for. The coin is a 4, and currently is owned by 17,878 members.
But as I showed above, a coin could have a different NRI but with the same amount of owners, and I believe this is due to how in many years and/or varieties the coin's struck.

The USA Memorial cent coin now also has a rating of 2. That is the 1982 to 2009 Zincoln, not the earlier copper one. British 1p is still 3.
I think the Japanese 1 yen should be down there too along with Chinese 1 Jiao and 1 Yuan. Some Euro coins from the big countries of Germany, France, Italy etc should be low too.
I love coins
