I think he is asking why his coin doesnt appear to have a laureate bust like the second coin, but rather a plain bust.
I have no answer either....so let's get our in-house expert to chime in... @David Atherton Are you available???
The laureate version, RIC 1288, is listed as 'Common'. The bare head version, RIC 1289, is listed as 'Rare'. Hope that helps.
