Agrippa As Authenticity?

Similarities yes
But not the same ......
First thing I noticed was the very obvious BD on the reverse complete with the pitted scar above the C
Very unlikely to be seen on a modern fake and the reverses are plainly different
The obverse are much more alike
But not the same
If you draw a line following the back of the head of Agrippa
Coin #1 leads to the bottom of the C in the legend
Coin #2 leads to the O
The jaw also points to different letters
There are enough differences to safely say the two have no connection

But as Agrippa is commonly faked you are always wise to be suspicious !
I think #2 is safe to assume as genuine
Number 1 is probably genuine
