unidentified coins [solved]

I would like to identify the 3 coins whose photos are attached.

Hi,

First things first, you need to provide some data about them. Their diameter alone will greatly help narrowing the search.

And photos must as well focused as you can.

With that said, the first coin appears to be from medieval islamic states, the second coin appears to be from italian states (if it's not some sort of religious medal), and the third coin is a Byzantine follis.

Coin #2 appears to be an imitation of a gold coin of Venice, Aloysis Mocenigo.  With more information , the type might be identified.

Coin #3 appears to be a Byzantine follis.

When more information is provided, such as the size and the weight, more help is usually possible.  

Third coin is a Justinian I follis.

Thanks for the answers. Here are new photos with better focus.

Information:

Coin 1 - approximate diameter 24/25 mm. Composition and weight appears bronze.

Coin 2 - approximate diameter 19 mm. Composition and weight appears silver.

Coin 3 - approximate diameter 30 mm. Composition and weight appears bronze.

Because the 3rd coin has what appears to be 2 figures, I am thinking a Justin II and Sophia  Byzantine type. Similar to this:

You need a scale my friend. A decent small electronic coin scale would run about $12 - $15 U.S. They really help in the identification of coins such as this more difficult and worn example. 

Coin 2:  ½ Zecchino - Alvise Mocenigo II - Republic of Venice – Numista

Since yours is not gold, it is a replica.

Coin 2:  ½ Zecchino - Alvise Mocenigo II - Republic of Venice – Numista

 

Since yours is not gold, it is a replica.

True, but looks like a replica of a Zecchino not a half Zecchino.

Yes, you are correct, the inscriptions match the zecchino.

The size more closely matches the half.

(all the more evidence it is not authentic).

On the front it says "SMVENT - DVX - LOV MOCEN." Couldn't it be an uncataloged version in silver whose author is ?LOY MOCENIGO?

There are silver coins of Alvise Mocenigo but not with such a design.
