Metal Identifying [solved]

I have a 2 Pounds - Elizabeth II World War II 2 Pounds - Elizabeth II World War II, and I don't know whether it is gold or not, how do I test if it is or not?
It's probably not, as i found it in circulation, but it has a small chance, as a young child may have opened it and put it into circulation.
Thanks,

Specific gravity test. Very easy to do if you have decent scales.

Do you mean this one https://en.numista.com/catalogue/pieces13389.html ?

​Yes

​Umm, I'm Slightly Confused In What You Mean!

The specific gravity of brass is around 8400-8700 (kg/m3)
For Nickel it's 8800
And for gold it's over 19000.

So if the coin's dimensions are correct, then it would weigh over 35g (for pure gold anyway)

This document shows how to measure a coin's density.

Or you do like a Pirate, and bite the coin, see if it bends!

But nevertheless, that's a great coin to find in your change.

Edit.
Actually, scrap what I said about the weight, even the gold one is 15.98g, but it should be thinner.

​Aye, I Was About To Say, The Weight Is The Same, Will Check Thinness
Thanks For Your Help!

EDIT
Thinness Is Exactly 3mm

This thread has a discussion about the coin, and estimates the gold one at 1.4mm, compared to 3.5mm for the base metal one.

Eh, So it's Not Gold, But Still A Lovely Piece Of History And A Great Surprise To Find It In My Spare Change
Thanks For Your Help!
