One reason I love this hobby and one of the things I love to do is attribute unfamiliar coins. After 27 years in the hobby unless the coin is really really worn I can instantly attribute as to emperor, and in many instances if some of the inscription is visible it is usually an easy attribution. But for Greek coins - bronzes - and if there is no inscription at all on provincials the task is not so easy. Here are two coins that hours of study have not resulted in an attribution: 18mm, 4.83 grams. There appears to be an inscription around the right field in front of the portrait. As I write this, I think this is one of the coins struck to celebrate the battle of Actium under Augustus. It does appear to be early empire - but under which emperor? Next: 16mm, 4.13 grams Note the laurel wreath on this coin which indicates provincial. The beardless portrait and overall look indicates Vespasian or Titus or early Domitian - is that a fish under the portrait? I am not sure if the reverse is upside down. It looks like ..KPAT[lambda] in the inscription but that is no help. I really do post these only as a last resort - but I think I might have the first one - as often happens I know I have seen both of these before but where?
Your first coin looks like Tiberius / sulcus primigenium Tiberius usually has a “square head” like on your coin, while Augustus has more like an “egg head”. Troas Alexandria RPC I 1656 (Augustus) or RPC I 1657 (Tiberius) https://rpc.ashmus.ox.ac.uk/coins/1/1657 https://rpc.ashmus.ox.ac.uk/coins/1/1656 It could also be Caligula
there is clearly part of an inscription on the front of the portrait - I think I can make out two greek "I" "lambda" (lambda for sure, "I" is iffy) letters and hopefully "Greek Coin Inscriptions" can take it from there
