Post Your Tiny Coins!

My smallest coin (so far) --

Hungary, 1131-1141 1 denar -- diameter = 9mm:

A few fun examples:

Itty bitty 6mm barbarian copy of a Roman coin, probably a third century Antoninianus (the mints in England would hack a half dollar size sestertius and make dozens of these little things)



A collection of tiny Indian gold and silver:



The gold ones are Fanams; in their day they were worth so little that a farm-hand was entitled to no fewer than 4 per week so that he could at least afford enough food so that he wouldn't starve to death. The one with Arabic writing is from the Tipu sultanate, 1214 AH. The rest I think are from either Travancore or Dutch Cochin, all 1750-1850 time frame. The silver one with geometric shapes is a Travancore chuckram, 1800s. Small silver with Arabic writing is from the Sind dynasty, around 700-800 AD.

I really like that Colombian 5 cent.

This one is only 13.2 mm...

Algeria 1 Centime 1964 #94 16mm

The answer is definitely yes: here's one.

Mind you, dealing with 5mm coins can be a bit perilous...

I want to know how many were lost by simply falling out of someone's pocket.

@CoinCollector2012, that was actually the exact reason why the Panama Pill was discontinued, and also why the silver trime never caught on. As for countries that used even smaller coins for centuries; I am not really sure how they coped, but I am sure that is the reason so many are dug up as metal detectors get more sensitive.

Fun fact about the tiny Indian coins I posted; they were actually so difficult to handle without dropping that anyone dealing with a large number had to invest in a special counting board:



You would drop a handful of coins on there, and shake it until the holes were filled.

Smallest I have is 1865 Maximilliam silver token, 11.5mm .3g ASW Hey I'm rich!
