My smallest is the Spanish 1 Peseta (1989 - 2001) which is 14mm. Clearly not the smallest around, but as it is made from aluminium, I would guess it must be one of the lightest at 0.55g.
I have some South South African 1 cents (15mm) available on swap. They are not minted anymore and if the interest is good enough I will add more to my exchange list.
...but I do have a golden ducat Franz Joseph 1904 (not on the Numista site) which has a diameter of 11mm.
That's my smallest and beautiest at the same time.
Smaller do exist (e.g; Maundy pennies), but the smallest circulating coin in my collection is the 5 cents from the Netherlands, minted in silver, 0.640 fine. It is 12.5 mm in diameter for a weight of 0.685 g (strange it only came up once in this list.)
I recently purchased a 1/3 Farthing of 1885. It's not my smallest coin, but at 15 mm you can consider it as really tiny! By the way, what was the purpose of these coins? Numista says they were minted for use in Malta, but why did they need coins with such a low value? Was the Pound Sterling worth more in Malta or something like that?

A new smallest coin has just entered my collection, previous one was 11.5mm, this one is 11mm, so the difference isn't that big, but still it is a new smallest one:
A Nauru 5 Dollars gold coin, it is so tiny that the Lincoln cent is almost as big as the capsule/casing protecting the coin.

Most of the coins posted so far are relatively huge in comparison to the following coin in my collection, but there are other smaller coins out there :
Vijayanagar: Anonymous (ca. 1406-1450) AR 1/4 tara (MCSI-498)
Also have 2 x 1850 Dutch 5 cent coins of William III - they are 12.5mm in size.
I love coins. Especially silver, gold and anything really old.

The smallest circulation coin in my collection is this Travancore 1 Cash coin, shown next to a 1 Pice from India. What is odd about my 1 Cash coin is that the diameter is smaller than the diameter mentioned of that coin in the Numista catalogue...
Besides coins I love geometry. The avatar consists of each of the 35 hexominoes used precisely once. With the 5 large yellow shapes placed like this, the solution for tiling the remaining 30 hexominoes is unique.
Not much larger than the maundy penny are these teensy Dutch 5 cent coins,
Not the greatest condition, but the 1850 dated coins are 12.5mm in size and weigh about 0.5 of a gram - no wonder it became a nickel and then copper coin!

Cool coin Don, that I believe is known as a "Mite" the smallest denomination ever.

I just got 3 pieces of tiny Chinese Western Han elm seed Ban Liang coins; 157-141 BC. The weight is 0.04-0.05 g and diameter 4.5-5.5 mm. Next I will try to take some photos.
Most of my smallest coins are around the 15mm mark but the only coin that is the smallest in my collection is the 1989-2001 1 peseta coin from Spain coming in at 14mm.
here is a small list of some of my small coins.
1951-1978 5 céntimos from Costa Rica 15mm
2000-2017 1 centavo CUC from Cuba 15mm
1925-1935 silver 10 centavos from Mexico 15mm
1961-1991 1 kopeck from Soviet Union 15mm
1909-1942 10 öre from Sweden 15mm
Hi to whoever is reading this. Did you know that TYPEWRITER (on a QWERTY keyboard) is the longest word you can type using only the letters on one row of the keyboard.
Good thing someone revived this thread! I don't quite beat some of you (6mm coin is insane!) but I think I'm not far off! Mine is this: https://en.numista.com/catalogue/pieces253913.html
(The actual one in the picture, 9 mm on the larger side and 6 on the smaller one)
It's also my oldest coin and I love it so much! A curious fact, it's countermarked, and it's smaller than a countermark on another coin I own (which turns out to be my largest coin!)
Actually, when it will be delivered to me (hopefully this next week), also this nice Liechtenstein 10 Franken 2019, half gram of .999 gold, will share this record with the above-mentioned Hungarian one. https://en.numista.com/catalogue/pieces159900.html
Fun fact: that exact coin was actually used as a basis for the size of the hole on a CD! Meaning you should be able to squeeze one through your copy of Shrek II on DVD.
That Dutch small 10c is amazing, the normal size of that coin is tiny enough already.
My smallest ones now are Maundy pennies of which I have several.
All of these coins are just 10.8mm in size and weigh just 0.47 grams each. They did not really circulate being given out in a ceremony and made in the low thousands except for proof sets, in which the number went up to 26,000 in one case (1937).
This image of a proof set gives you an idea how small they are. The biggest coin is a 32mm half crown.
The smallest fully circulating coins I do have are these 3 halfpences issued between 1834 and 1843 and 1860/62 and they were issued for the West Indies so women in churches could donate a silver coin each week (They did not like coppers). The coins briefly circulated in the UK. Just 12mm in size, these tiddlers got lost very easily. Numbers minted were quite high with well into 6 figure mintages most years and 1842 saw a large issuance of nearly 2 million pieces alone. I have 4 of them.

Some real classics there, the half farthings and third farthings were for colonial places. The thirds were for Malta, who used it to replace a tiny copper coin called a grano - only a few hundred k were minted and they never caught on. They were minted a few times between 1827 and 1913. Your coin is the 1902 one, the second to last date of it.
Half farthings were originally minted for Ceylon (Sri Lanka), but in the 1830s and 1840s they caught on in the UK too. There was also a quarter farthing issued in a few years only and these are very scarce (I don't have one) - again for Ceylon. All of these weird coins (4d, 1½d, ½farthing, ⅓ farthing and ¼ farthing) were minted in this 1834 - 1844 period, when they were trying various things at the mint and seeing what stuck.
