Unknown coin roman or greek?

Apologies in advance for the really terrible pictures, I am currently in a move, so these are the best pictures I can take right now(taken during the eveing).1st coin is about 13mm, the weight I have not yet tried to take. Any information about the following coins would be very helpful

2nd coin is about the same in MM but very thick.

First coin comes from here https://www.wildwinds.com/coins/greece/judaea/askalon/t.html

Second coin is Roman from Alexandra, the emperor i am Guessing Probus or Diocletian.

For the second coin, I wonder if the obverse doesn't say ΥΑ(Λ)ΕΡΙΑΝΟC CΕΒ, which would be the emperor Valerian?

The Alexandria Tetradrachm is Numerian, like this (but not necessarily an exact match)
