Ancient coins from estate sale!

[Punatic]

Hello-

Have not posted in awhile as my treasure hunting priorities have shifted a bit to toys rather than jewelry and coins

I do come across some cool stuff occasionally and got these today. Any help identifying and an estimate on value would be appreciated! I did do some preliminary research but there are so many variation on these I'm a bit lost!

Thanks in advance for your help!

Alexander the Great Greek drachm with Zeus. Nailed and I think from 336-323 BC
Antonius Pius Egypt AD 158

Were any of them authenticated?
If not, be cautious, one or more could be replicas.

Yes I was wary and have not paid for them yet. Any tips on how to authenticate?

Tell the seller to get them authenticated with Certificates; then, (if you're not familiar with the authentication company) post that company's name here to see what response you may get from other TH-ers who may have done business with or have an opinion about the authentication company. Otherwise, to be safe, consider them as replicas and price/value them accordingly.... IMO
