Need Help Identifying These Ancient Coins

@eric, I'm interested to hear what others here say, but I'm concerned about some of these being cast fakes. I'm by no means an expert, but the mushy details and porosity make me lean in that direction. In the very last pic that you posted, it appears as though there are bumps on the eagle's neck and right thigh. I don't know how that happens on a real coin with this level of wear. Did they come from a reputable source?

Please in the future only post one or two coins at a time. Could be the lighting but the silver coins all look like they have been polished. The first coin appears to be genuine but will need better pictures to tell for sure. #2 is Severus Alexander this one looks good. #3 the Septimius Severus is a fake. #4 the Tyre Shekel is also a fake. #5 Not sure, don't like the look of the eagle. #6 the Trajan Decius is genuine and the last coin is the same as #4 and fake.
