Help on identification on 2 Roman coins [solved]

Hi everyone,

I have 2 Roman coins I cannot identify. I took pictures, but realised that they are not sharp enough. I can redo them tomorrow, but maybe someone can help anyway:

Here is No 1:



As far as I can see, front is a man with a crown, I can read only some letters"...stumus..."
Back is a women with a helmet and a spear...since I cannot decipher the letters - maybe some are Greek?

Here is coin no 2:



Front I can see 2 men, one giving a crown ( or laurel wreath) to the other one.
Back a man with a crown...

Any help/hints are appreciated, thanks a lot in advance. Please excuse the bad quality pictures!

Both coins are easily identifiable once clearer pictures are posted.  I have an inkling on both coins, but will wait til clearer pictures are posted  

a very good word search can be found here:

they both look roman
The name around the head, starting left, is the name of the emperor.
The 3 last letters are AVG

Thanks for your efforts!
So I went to my neighbour to get a decent camera. Here are better quality pictures:



Number 2



I still have difficulties reading the letters...I guess I am just to blind or stupid...

Attribution for the first coin is as follows (more information at http://wildwinds.com/coins/ric/postumus/i.html):

Roman Empire: Postumus (260-269 CE) AR Antoninianus, Cologne Mint (RIC V, Part II-318)

Obv: IMP C POSTVMVS P P AVG; Radiate, draped, cuirassed bust right
Rev: PA X  AVG; Pax standing facing, head left, branch upward in right hand, transverse scepter in left; P in left field

The following coin is NOT mine and hence is posted for illustration purposes...

Great! Thanks a lot!
Indeed the link you sent is a valuable source!
So one has been identified!!

This one was harder as multiple coins fit the bill and the legend was a bit difficult to read, but I think I cracked it (see http://wildwinds.com/coins/ric/valerian_I/i.html):

Roman Empire: Valerian I (253-260 CE) AR Antoninianus, Uncertain Syrian Mint (RIC-287)

Obv: IMP C P LIC VALERIANVS P F AVG; radiate, draped and cuirassed bust right
Rev: RESTITVT ORIENTIS; Oriens, turreted, standing right, presenting wreath to emperor, standing left, holding spear

The following coin is NOT mine and hence has been added for illustrative purposes...

Thanks a lot! Great work!
