Can you identify them? They can be either current or non-current, but not prior to the modern coin era (e.g. hammered, etc.).

The Australian 50 cents coin may be a candidate: it measures 31.65 mm in diameter and weighs 15.5 g. As for the smallest and / or lightest coins, I have no suggestions.

Thank you. So here are the full specifications from numista:

Metal   Aluminium
Weight   0.7 g
Diameter   14 mm
Thickness   1.95 mm

That's a full 4 mm narrower than the UK 5 pence.  >:(

The 1904 Panama 2.5 centavos ("Panama Pill") is just 10mm. I think it's one of the smallest machine struck coins. Certainly not the lightest at 1.25g though.

Not sure where exactly the "modern" cutoff is, but the 1797 "cartwheel" twopence comes in at 41mm and 56.7g. Chronologically later (mid 1800s), China, Vietnam, and Japan all made massive cast coins well over 40mm. I can't think of any other modern circulation coin larger than the "dollar" which usually does not exceed 39mm.

There were some monster 5 kopek coins in Russia at a similar period to the British Cartwheels.

But nothing really can beat the 10 daler kopparmynt Swedish plate money, at ca. 19 kg.
