Roman coin [επιλυμένο]

Hello, I am looking for more information on this coin. I believe it is a nummus 19.5mm, the obverse says CONSTANTI NVSMAXAVG and the reverse says PROVIDEN TIAEAVGG though I am not sure about the letters beneath the building. I was not able to find this coin on numista, any input would be appreciated. (Also if anyone has any valuations)

This one looks close.

Nummus - Constantinus I (PROVIDENTIAE AVGG; Nicomedia) - Roman Empire (27 BC - 395 AD) – Numista

Thank you! I don't know how I managed to over look that one. Upon further inspection it appears to be the 6th officina variety. 

Would you have an idea as to what the value of this coin is, because I've seen some roman bronzes be fairly inexpensive but others quite expensive. And I am not experienced enough on roman  bronze values.

Sorry, I don't do values especially for the ancients.
