It's definitely a coin.
I concur.
You never know, it may even be worth a bazillion!

Whilst I'm not a coin expert, i know my metals and corrosion. That ain't old.
That's a Roman coin of the Jovian age, and that fella was only Emperor for 9 months.
If it's gold, it doesn't corrode.
Is it actually a gold coin?
Similar coins on ebay going for £500-£2,000
Google image search: gold Roman coin.Only if it's pure gold. Which it's not likely to be. It would be an alloy. Which does corrode..
A friend of mine found the below coin in their garden the other day and she's asked me to help her find out what it is and more importantly if it's worth anything.
It looks Roman to me but what do I know. Does anybody here know anything about coins or where she can take it to find out what it is and how much it might be worth?

Do you not have to declare this to the county coroner? Treasure Trove rules may apply.

Try biting it, then you'll know if it's chocolate.
Evidently you don't 'know your metals' very well. Or perhaps you don't work with gold much?
Gold does not corrode in ANY way (apart from when submerged in certain acids - like hydrochloric acid). Gold coins and other artifacts buried in the ground (or kept anywhere else) will come out hundreds (or a thousand) years later in pristine, totally untouched condition - absent any form of corrosion. All they need is a good wash.
