The only one that has a chance of being authentic is the first one, the
Neapolis and I'd say it only has a 20% chance of being real. The others are bad for certain.
Why are the others bad....The
style is wrong, the flans are wrong, the surfaces are wrong etc...
I could probably be more specific but if you are new to coins and don't know what you have, you probably wouldn't understand why they are
fake. If you really want to understand the coins you have, study a
bit and use all the online sources you can find and you will gain a better understanding as to why they are bad.
To
help you learn, what you have copies of are:
1 -
Neapolis Nomos
2 -
Geta Laodicea mint denarius3 -
Alexander III Stater - should be gold not silver
4 - Otacillia
Severa - doesn't correspond to an authentic
denominationDo some searching on these and see what you can come upo with and learn what they are supposed to look like.
