Another way to check if it's silver is to place a known silver coin, plus a CuNi coin plus the Badge under a single white tissue.

Silver will show through as white, CuNi will be grey, and the badge should be one or the other. If the tissue is thick, you might need to separate it and just use one ply. Not very scientific but it usually works on most silver.

Silver v Cupro Nickel, silver coin is on the right.

OK we've completely cleared that up now. :nea:

According to Triggers' suggestion it does draw a line so it's silver.
According to Nancys' suggestion it looks copper-nickel under the tissue.

It has some toning that might have impaired the experiment under the tissue.

I also tried Steve's method and it worked. :angel:

Mark did a specific gravity test and it suggests it's silver.

We measured it at 10.6.  Given that copper and nickel have an SG of about 9 and silver is 10.5 it's safe to assume it's silver.

Well this discussion has educated , not only me, but may I suggest a lot of others who are reading these comments.

Now I have learnt how to positively identify things that are silver from those that aren't.

Many thanks on and all.

The tissue trick is a bit less reliable with coins with a low % of silver in them. :angel:

I have tried the tissue test but it does not seem entirely reliable
but it might be dependent on the amount of bleach and stuff in the tissue as well

by the way - lovely badge pp

Maybe we need to add this to the Wiki.
