Old Roman Or Greek Coins

Both Tetradrachms from Alexandria.
Better photos would help with Id.

I think the photos are actually decent enough, especially for a first try, & more than adequate for the purpose of attribution, not that I've researched them yet on that basis. The first portrait is really quite Neanderthal looking, isn't it? I'm thinking the second one resembles Severus Alexander. I feel confident somebody here will recognize these.

Thank you all for your comments and information Palouche the first coin

looks right to me thank you. The other one the bird looks a bit different. Re the bronze disease how would I treat that please and if it ok for me to wash coins with soapy water or should I leave them as is?

Thanks so much for your help I have a few coins that I know nothing about I sent a picture of one to a coin collector and he said its a fake because if it was real it would be rare. I guess that one will be my next post.

Thanks again

Thank you Paul I will do that, re other coins should I only wash them in distilled water or can I use soap.

Many Thanks
