Rarest Coin in Your Swap List (by NRI)

Hi all -

Whenever I add coins to my swap list I always peek at the Numista Rarity Index (NRI) for curiosity. I know the number doesn't reflect actual rarity (ie: mintage figures) or value, but it's still a fun curiosity. So I'm wondering, what's the rarest coin in your Swap List?

For example, I did a quick survey of my swap list and here's what I found:

a) 1988 South Korea 5000 Won (Boys spinning top) (https://en.numista.com/catalogue/pieces23044.html)

NRI: 64 / Mintage: 227,500

This is a non-circulating silver coin, part of a proof set so I'm not suprised by the higher NRI

b) 1943 Nicaragua 5 Centavos (https://en.numista.com/catalogue/pieces14303.html)

NRI: 42 / Mintage: 2,000,000

Certainly not rare, but a pretty high NRI for a standard circulation coin

c) 1968 Uganda 5 Shillings (https://en.numista.com/catalogue/pieces10037.html)

NRI: 20 / Mintage: 100,000

Given the mintage figure I expected this to have a higher NRI. I guess it's a pretty popular swap coin!

d) 1973 Jamaica 1 Dollar (https://en.numista.com/catalogue/pieces10374.html)

NRI: 20 / Mintage 10,000

Another surprisingly low NRI given the mintage. I guess we all like our Franklin Mint coin sets?

So collectors - let's see what's the rarest coin by NRI in your swap list! Maybe we can make some trades?!

My collecting is based on my interests and not on rarity or value of a coin. There's so much beauty in some "cheap" and common coins while some rare and expensive ones are quite dull and unattractive.

NRI 87

well, a little cheating because I did create the page and own the pictures for this one.

But other people have it to swap so the NRI has actually gone down slightly!

@FlyingRedPanda -

Very interesting piece! I hadn't seen that one before...

@Dejan -

Of course, you're right...! For example, I'm a big fan of Lincoln Wheat Cents, which have a low NRI (3), but many - if not most of us - still collect them by Date and Mintmark. Same thing with Swiss francs and rappen. Very common but I love the LONG date runs because the designs rarely change! I created this thread out of curiosity - what are some uncommon coins (as defined by NRI) in our swap lists? I'm hoping to find some uncommon pieces that I didn't even know I wanted :)

My swap list is tiny - it's mostly accidental duplicates, and mostly banknotes. (And I'm still not sure if I would ever end up doing any actual swaps.)

That said, I did recently add this coin, an obscure(ish) German States issue with a NRI of 31.

This coin, which I absolutely adore has a rating of 95

https://en.numista.com/catalogue/pieces160813.html

So does this coin

https://en.numista.com/catalogue/pieces160817.html

And so does this coin

I believe a 95 means only 2 collectors have it

Sorry, not have my glasses on

Third link a duplicate of second link.
And yes, 'I believe a 95 means only 2 collectors have it', correct.

Altered the above. Thanks for tip off.

Glasses are a must, I'm afraid

It has been many years since I have swapped or updated my swap list. Working on it now.

As it stands, https://en.numista.com/catalogue/pieces118084.html with an NRI of 54.

I'll give everyone the "heads up" when I'm done.

Thanks for all the replies. Keep them coming!

I wanna see what's the rarest coin in your Swap List...  :)

Maybe we can make a trade!

97 NRI is my highest but personally i find this to be the rarest by numista standards

https://en.numista.com/catalogue/pieces199765.html

And heres one of my 97s

I have quite a lot of 97 NRI coins in my swap list, especially within Russian wire coins, also some Golden Horde.
Welcome to see and offer something:)
