Hi.

It's detailed on the french version of this coin:

Copper 75%

Nickel 25%

N#17720

Don't know why this is not indicated on the english sheet…

Additional details is a language dependent field.

Cupro-Nickel is an alloy - not attracted to a magnet.

 

Pure Nickel is attracted to a magnet - being an element.
