Dear All,

Thanks beforehand!

Hello

Qian Dao Yuan Bao

but these coin are in iron…

Except this one but diameter is off

N#218460

Thank you for informing!
///
But my is not magnetic
///
Also it has strange diameter 18mm,
not listed at Numista
///
Also there is nothing on reverse,
could it be a real one?


 

I don't think it's genuine but I'm not expert

No many silver coin was made in China

The only one with the same diameter is in iron 

What is the weight ?

And the thickness?

I don't have exact wages unfortunately
///
It is between 1 and 2 grams
thickness is about 0.5mm
///
Could it be lead?

no lead coins for this series…

Could you please give a link 
to the same diameter 
18mm 
coin of Qian Dao Yuan Bao
///
Thanks a lot!

It's the Hartill 17.108 around 19 mm but no pics on Numista and in iron
