6x Roman Republican silver denarius (Modern Fake? Genuine?)

[Norbert K]

Hello everyone,
 I got a collection of 6x Roman Republican silver denarius.
Could anyone help me identify if they are genuine or modern copies.
Their weight seems to be lower than what I can see on other examples.
Many thanks,
Norbert

Terrible and obvious cast fakes

Here are 2 cast twins of your CREPUSIUS cast fake, there are on all of them edge cracks on the revers at about 10 o ´clock and same centering and wear and flan shape.
