#25 left is a silver coin of Domitian or a fake pretending to be. If it is not silver, it is fake. I strongly suspect #29 and #30 are also modern copies. #31 could be but I'm not all that good with Sasanians. You did not ask for ID's but for what we thought. This looks like the kind of bulk lot you get from buying the low end sort of uncleaned ancients and then clean them poorly. Several are identifiable but not so much what we would call collectable in this condition. Cleaning will not help in most cases. This is not most of our opinions of the way to start in the hobby. If you want help with ID of the better ones, make an effort and post what you se and learned one at a time for review/help.
I'm sorry I thought he was asking to ID them all in which case this thread would be mind-bogglingly complex.
