Some More Roman Coins Need Id, Thanks In Advance

Quite a nice bunch of coins.

#1 is Probus.
PROBV-S PF AVG - Bust right, radiate, cuirassed.
VICTO-RIA AVG - Victory walking left holding wreath and trophy.
The mintmark could be 'R thunderbolt sigma', 'R wreath sigma' or 'RT sigma'.
RIC V-2 Rome 215 - Minted Roma 276--282AD.

#2 is Valentinian I.
DN VALENTINI-ANVS PF AVG - Pearl diadem, draped, cuirassed.
SECVRITAS-REIPVBLICAE - Victory advancing left.
I cant read the mintmark, it could be one of about 70 combinations from around 13 mints. Minted between 364 and 375AD

#3 is Claudius II. I'm not 100% sure on this one but I think its:
IMP CLAVDIVS AVG - Right, radiate, drapped.
PROVIDEN AVG - Providentia standing left, legs crossed, leaning on a column with baton and cornucopiae, globe at foot.
No mintmark
RIC V-1, 90 Rome - Minted in Roma between 268 and 270AD.

#4 is Valens.
DN VALEN-S PF AVG - Pearl diadem, draped, cuirassed.
SECVRITAS-REIPVBLICAE - Victory advancing left.
OF in left field II in right.
CON star, perhaps just CON - Minted in Arles 364 to 378AD, RIC IX Arles 17b, type xiii(b or c).

I'll come back to the others when I get a bit of time if nobody else does them first.

thanks a lot, will do :)
