Hi, managed to pick these up cheap and took a chance because the coins were in a Pobjoy mint velvet case. After doing a little research online I could find no evidence that the Pobjoy mint ever actually struck these coins so I think the coins themselves have just been put in the case
Is anyone familiar with these? I'm trying to determine if they are definitely silver.
It says the CuNi version was 27g and the 925 is 28.28g. Mine actually weighs 28.5g, so with my dodgy scales I'd think it likely silver. Both have a mirror finish.
Many of modern crowns are made of multiple metals - there are Cu-Ni issues as well as silver. If a coin came from an obscure source it may be tough to establish its content. More likely cupro-nickel though.
Yes, infact since the one I got is a $1 Sierra leone coin not $10 and my world books of coins lists lots of CuNi Sierra Leone commemoratives as CuNi and 28.5g (although not this one) I think (unfortunately!) you are right.
