Hi
I have a gold coin and it has been tested and it is gold.
I have asked what it could be on other sites but nobody as a clue it is 10 grams in weight and as you can see it is worn but you can make out a male bust on the front of the coin.



Any help to identify it is most welcome thank you.

I have never seen a gold coin that looks so corroded.

To be that corroded It has to be an alloy with a high amount of copper
Gold is the most non-reactive of all metals and is benign in all natural and industrial environments. Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Gold tarnish is usually very thin and shows up as a darkening of reflecting surfaces. Pure gold is a noble precious metal, and the least reactive of all metals. It does not rust, nor will it tarnish. However, because almost all gold manufactured items are not pure they will rust and tarnish.

Whoever tested this coin for you was pulling your leg, it is in no way gold. What I can make out the coin appears to be either Roman Provincial or Greek and is made of bronze. I don't think there is enough detail to make a positive ID, but I'm going to move it over to the Ancient coin section, were it might be identified.

Sorry, ancient gold does not look like that. It looks pretty much the way it was when it was put into the ground.

Thanks everyone it was purchased as a joblot of coins at carboot sale (garage sale)A friend tested it with nitric acid and there was no reaction.
Does nitric acid not react with bronze or copper.
I was unsure myself and that's why I got I checked out but maybe it is bronze or copper because I thought the same that gold would stay untarnished and in good condition.
Thanks again

There are standard ways to test for gold-any jeweller or coin shop has a test kit. Without knowing exactly what was done and seen I would say that this is NOT proven to be gold.
