Found the first one
Justin II half follis

 

[Mackaydon]

"K" coin is a half/semi (20) 'nummi'. Byzantine, from about the period of 565-578 IMO.
The mintmark, KYZ represents Cyzicus, an ancient city on the western shore of Turkey.

Thanks useful information.

 

[Mackaydon]

BTW, the letters to the left of the K spell ANNO, as in year. And if it could be read, the year of the monarch's reign (in Roman numbers) would be shown to the right of the "K" (possibly a Roman "III").
Don...

As ivobg and Mackaydon have already stated correctly one of the coins is a Byzantine AE half-follis between AD 565-578 showing JUSTIN II and SOPHIA - minted in Cyzicus.

The other is the more common Type 15a SISCIA minted AE3 of VALENTINIAN I AD 367-375 with legend DN VALENTINI – [ANVS PF AVG] and reverse SECVRITAS-REIPVBLICAE Victory advancing left with R in left field and •[?]SISC in exergue
