Hello,
Top one is Crispus, Constantines first son. This is what it would have looked like:

FL IVL CRISPVS NOB CAES - CAESARVM NOSTRORVM, VOT X (prob '.X.') in wreath
Cant really see the mintmark, maybe 'TS∆VI'? If it is it would be Thessalonica. Minted around 324AD.
Bottom one is as Wei Fun says, Constantine. Another example here:

CONSTAN-TINVS AVG - D N CONSTANTINI MAX AVG, VOT / XX in wreath.
Mintmark 'SMHB.'? If it is its Heraclea mint, dates from around 320AD.
I agree with Wei Fun as to the values but these two characters have a very interesting and rich history, Google them ;).
