After another look at the larger piece (squarish flan, the patina looks black on my monitor) this, I believe, is a sestertius of one of the later Antonines. Could be Marcus Aurelius (1st most likely), Lucius Verus (least likely) or Commodus (2nd most likely) – on the basis of what appears to be a beard on the chin of the portrait – again, no obverse legend and not clear enough of a portrait for me to feel confident assigning it to a specific ruler. This puts it in the period 161-193 AD.
The reverse is a standing deity or personification, but it’s so short of detail that I am at a loss to tell which one of a couple dozen possibilities it might be. If I had to guess, however, based on what the posture of the arms, etc, appears to be, I’d say perhaps it’s Spes standing left holding flower and hitching the hem of her skirt. It might also be someone like Pietas standing left sacrificing over an altar at her feet. Or it could be someone altogether different.
Sorry I can’t get any closer with these – some of them have useful hints visible, some don’t.

Rx: VOTA PVBLICA IMP VIIII COS III S – C. Aurelius standing left sacrificing over tripod altar.

Just a guess, but what little detail I can make out on the coin seems to make a pretty good match with the devices on this fairly common M. Aurelius sestertius.
