Roman coins identifation

Dear fellow coincollectors, 

I bought for the first time in my life some Roman coins. And I immediately understood why I waited so long ;-) this is so difficult, so I could really use your help. Highly appreciated. 

Coin 1 is 31mm diameter, thick 4,1 mm and weighs 22 gram.

Coin2 diameter 32 mm, thick 3,9 mm and weighs 22 gram

Coin 3 diameter 28,6 mm thick 2,5 mm and weighs 8,8 gram

Kind regards

Thank you

I found the coin thanks to you,

On the first coin, what do you read ? XII

So: ANTONINVS AVG PIVS P P TR P XII / COS IIII / S|C or … something like that :)

and …about the samething for the second AS
