Smallest coin you own?

This seems like a fun thread to start. I've got a few small coins, but this is certainly the smallest, and particularly lightest at 0.5 grams, coin that I currently own. Isn't it just the cutest little thing? What kind of micro-coins do you have? Please feel free to share them here!

The tiny coin is just to the left of the "T" in "UNITED" in case you missed it lol

This is my smallest so far
Histiaia. Tetrobol circa III-II century BC, Euboia. AR 10.5mm, 1.55 g.
Wreathed head of nymph Histiaia.
Rev. IΣT – AIEΩN Nymph seated r. on galley; below, trident. BCD Euboia 387.

 

These California gold tokens are probably more jewelry than coinage, but they are small.


For regular issue coins, the half dime is hard to beat. It is 15.5 mm in diameter.

 

Here's a couple of small ones. I haven't measured the sceatta but it's probably about 14mm.

 

I would imagine it must have been far more difficult to create coinage in ancient times as opposed to more "modern" practices. Admittedly, I am very lacking in knowledge of the ancient processes, but I'm pretty sure it wasn't very simple!

 

I've got a little one too.

Iran ¼ Azadi
.900 fine gold

The $10 American Eagle is for perspective.

 

Here is most of what you need to know

This gold Irish coin depicts the Book of Kells on the obverse along with a monkish scribe. There is an Irish harp on the reverse. The coin is only 11 mm wide. It’s a 2012, 20 Euro coin graded PF69CA.

The Book of Kells is a 9th-century illuminated manuscript containing the four Gospels of the New Testament, written in Latin. Now in the Old Library at Trinity College, Dublin. I’ve been there and seen it. No, they didn’t let me hold it.

I certainly appreciate the 1st page, but after the 2nd page being flooded with typical ads and pop-ups that bypass my settings, I understand the very basics of how they made their coinage. I'll delve deeper into the ancient stuff once I have more free time, but thank you for that reference!

 

Not to be too school-marmish about it but I think you meant 17 mm or 1.7 cm.

Anyway, cool little thing.

Here's another Diobol, Ionia, 1.07 g, 1 cm

 

Looks like my Peter The Great Silver Wire Kopek is the smallest coin I own.

This topic came up on another forum a while back and I was surprised how many coins I had that are smaller than a US dime (17.9mm). I'd have to look them up again.


Half dime is 15.5mm.

This one wins at 15mm. I have several from 1980s era travels. I don't think I have anything smaller.

 

From my small suite of Period One California Fractional Gold coins.
MS-63. $.25. BG 109

XF-45. $.50. BG 421

MS-62. $1. BG 530

I like the Period One coins because they were actually used in commerce. I wonder what it was like to use them as they are so small. How did one carry them around? How did a merchant store them? You would have needed delicate fingers to pick them up off of a counter and really good eyesight to see what denomination they were.
