Virenium

Hi. I've got a few virenium coins and they are slightly yellow/golden. However, I have this first day cover with a Gibraltar 5 pound coin: https://en.numista.com/catalogue/pieces81388.html




The coin in the first day cover is bright silver coin and slightly magnetic (sufficient to hold a strong neodymium magnet but not strong enough to snap it to the coin - if that makes sense). Virenium should be magnetic but previously I've assumed its always slightly golden in colour. Can anyone clarify or comment?

You have the answer yourself..... Google your alloy, quite easy by the way, and you can read it and the answer is there!

Hi Ole. I did use google and didn't find any definitive answers about whether Virenium is always a slight golden colour or whether it can be silver in colour. I thought someone could offer some help

I remembered this topic from 4 years ago ...

or this one from earlier this year ...

and so on - there is the Search on forum near top right.

It is an alloy mainly used for coins. It is a copper alloy plus Zinc and Nickel. The %'s are different from country to country.
In Portugal it was also used from 1927 to 1968 in coins of 50 Centavos and 1 Escudo, replacing older silver coins.
In this last case it was Cu= 61%; Zn=20% ; Ni= 19%.
