New To Coin Collecting.... How Do You Know If The Are Real?

If it came from a Notorious Fake Seller, then it's authenticity is on doubt.

Please do not test ancient coins for silver content, for two reasons: (a) if it is actually genuine, you've done damage to a unique ancient artifact, and (b) just because it's made of genuine silver does not mean the coin itself is genuine. Slavey and other fake-masters make fake coins out of real high-purity silver all the time.

If you're new to ancient coins, I'd strongly suggest staying away from ebay. There are far too many fake sellers on there. Find a genuine trusted guaranteed-for-eternity ancient coin dealer like Civitas or FORVM, or use a venue like VCoins where all the coins offered for sale are vetted.

If you post a clear picture of the edge of the coin we can see if there's a seam that would suggest it was cast.

I can't see a green camera option?

lol I think I need to try again!
