Looking again at the picture I posted above I am convinced the
obverse of Youngs coin is a die match with the
obverse of the BM example on the right (b/w image)
Look at 1 o'clock at the very long Γ of ΓΑΙΟΝ and its position to the
head, also look at the tiny A beside of the Γ in exactly the same position. Also the A behind the
head is in the same position.
