ID Coin Greek? Fake?

I hate to be the one to tell you, but any "ancient coin" a tourist might buy on the streets of Turkey will be a fake. Selling genuine ancient coins to tourists (or to anyone else) is illegal in Turkey, but selling fake ones is perfectly OK.

The one on the left is a fake decadrachm from Syracuse, on Sicily (Italy), a very famous (and valuable) ancient coin that is frequently copied. See some other examples on the forum here, here and here. I doubt if any genuine Syracuse decadrachms have ever been found in Turkey.

Not sure what the other one is a copy of.

If they were silver before then they are still silver now.

Joking aside, I have a few fakes that test positive for silver content. I would bet, though, it is only a silver plating at best. If you do not have the means to test the metal, most jewelers will be glad to examine the metal for free or a nominal fee. I would guess the coins are a modern alloy and thus probably worthless in terms of precious metal.

The artwork may appeal to you and a signet ring is an option, albeit, costly. I don't know the size of the coins in mm, but many collectors choose to take a fake coin and place it in an inexpensive bezel to be worn as a necklace. In fact, I have one around my neck now. One word of caution though. If the coin is an alloy, the acid in your skin may "eat" away at the side of the coin against your skin. You can purchase these bezels on-line and even at ebay very cheaply.
