Swiss 1919-B 10 Rappen. Any way to confirm brass?

Icollecteverything · February 2, 2019 6:15PM

These were made of brass or copper nickel with the brass being much more valuable. From what I see they both weigh 3.00 grams, is there any way to tell for sure the composition other than the color? I looked online and saw some certified as brass but also a few raw that people were claiming brass but appeared to be cu-ni.
I am 99% sure mine is brass and it helps there is a little luster around the edges but I sure would like to confirm it somehow.

The color is a dead giveaway on these

XRF is IMO, the only sure way

Thank you for the answers.
It looks like these are priced all over the place, or I guess that's the way everything is these days.

is the Cu-Ni coin attracted to a magnet?

I remember the pure nickel ones are, but I don't think the copper-nickel coins are attracted to a magnet.

I did try taking pictures but some of them made it look copper nickel and one even looked like grey steel. I have not tried a magnet yet but not sure about that working.
