Soth Atlantic Medal - Hallmarked or not?

I have just been told that all Falklands medals (South Atlantic medal 1982 I believe) are hallmarked.

Can anyone confirm or deny this?

Incidentally wikipedia states they are a cupronickel mix so not sure why it would be, but the pedant in me wants to know.


No it's not, the ACSM 94 was but not the new ACSM 11. I think MC are though.
