Thank-you. You have confirmed my suspicions. *Edit* Seller's comment. I found this lot of old Silver Ancient? coins when cleaning out my grand father's bedroom many years ago.
I'm not sure who the seller was trying to fool with those ....... I hate the old...found in my grandads wardrobe sellers.
The two Romans are Slavey Petrov products. The tetradrachm may be, too, but I'm not up on them. A real tip here is that the Julia Titi and the Pescennius Niger are both struck from the same silver (melted down European silver?) but her coins should be finer while his should be debased much more. If you had them in hand, you would notice they are way too thin for denarii of either period. Slavey charged the same for his copies of rare people that he did for common ones. You will see several of his Pescennius coins for every one Septimius Severus.
