The smallest bimetallic coin in the World

[ciscoins]

Can anyone say which bimetallic coin is the smallest in the World? I've found only one coin that is smaller than 20 mm: Kenya 5 shillings 2005 (KM#37) - 19,5 mm. And also I have an image of one trial coin of Ukraine: 10 kopeks 1994 (I suppose it must be 16,3 mm like all the other 10 kopeks). And that's all. Only two coins in all the World, and one of them is trial. Maybe you know some other bimetallics which are smaller than 20 mm?

How about Joseph Moore's "model halfpennies" of 1844-48?  These were also about 19.5 mm.

Thank you translateltd and Aditya. Now we have four coins: two regular and two trial. Ecuador 100 sucres is the smallest among regular coins.
