Thanks for the better images.
Definitely an FTR FH imitation.
The new image shows that it was struck and not
cast. Someone put scratches in the dirt (but it looks like they missed harming the black
patina luckily) with a pin. In the smaller images that gave it a wavy surface that I thought might be the result of a
cast coin. But with the better images it is now clear that it is struck.
Imitations like this are now known to be roughly
contemporary with the original
type. This small size means it was fairly late into the FTR era and into the next few years. The imitations stopped when high volume
coin supplies returned - generally with the Valentinianic
types that began in late 364. So you are looking at 356 - 364 as rough dating.
The
quality is quite
good.
