5 Roman coins? Identification, Need help! [επιλυμένο]

Hi all) Today I received a couple new Roman coins (i hope all of them roman) in my collection, can you please tell me by originality, tell me what kind of coins they are and how much they can cost? 

Thank you all in advance) 

1.  

2.  

3.  

4.  

5.  

Number 2: N#143480 

Number 3: N#114502 

Mintmark ANTΓ

Number 4: Constantine I commemorative follis “VRBS ROMA”
Mintmark not visible, this one have lots of varieties.

Still looking for the others but I can already say that 1 and 5 are from early empire due to the big SC (Senatus Consultum) in the reverse.

----------------------------------------------------

Numbers 1 and 5 I'll leave to the experts as I am unsure if my identifications are right.

#1 is silimar to N#253623 , and #5 is similar to N#246985 

1) N#253620

Giobruno took care of the rest, I'll just add values:

1) 5-10 €

2) 2-5 €

3) 2-5 €

4) 1 €

5) 20 €

These are all prices based on my experience buying and selling ancient coins. There is no priceguide for ancients and prices will vary. Too bad the Claudius was harshly cleaned, with full patina it would have been a much more desirable coin.

Thank you all so much, yeah its so hard to find original roman coins in a very good quality… Thank you all for your help)
