Ancient coins just received, can someone help please..?

Hello Ancient experts,
Ijust received these ancient coins amongst a collection and I have absolutely NOT the faintest idea what they are and if they have any value or not.
Hopefully someone can identify these and help with them.

I am working at the moment so I cannot give you a more comprehensive answer. I have no idea what C is, but the first coin is from the reign of Hadrian. The second coin is from the reign of Phiip. Once I have my references available, those two should be identified easily. However, I think you will get an anwer soon.

I agree with harasha about the first two portraits. Meethinks that the third is likely to remain a UFO, but we have some top notch people on this forum.
Coin B is a Philip I sestertius from Viminacium. Year 7 (Roman Provincial)
1st coin
Hadrian AE As. Rome (for circulation in Syria), AD 125-128. HADRIANVS AVGVSTVS, laureate, draped and cuirassed bust right / COS III, Roma seated left on pile of arms, holding Victory and spear; SC in exergue.
2nd coin
Philip I AE Sestertius. Moesia Superior, Viminacium, year 7 (AD 245/6). IMP M IVL PHILIPPVS AVG, laureate, draped and cuirassed bust right / P M S COL VIM, Moesia standing left, extending hands to bull and lion standing at feet to either side, AN VII in ex.
@YQQ If you provide the weight and diameter of the 3rd coin, it might help.
Thank you everyone so far. It is much appreciated .
Will do this later today as I am off with a group for a 5 hour hike.
well, I thought nothing easier than that..
but.. my GF cleaned my place (than you) very rigorously... and I am so far unable to find scale and caliber .....
it will have to wait until (hopefully) tomorrow
