This is an amazing coin
Where did it come from?
Lech illustrates a different coin: Mars advancing r., transverse spear in r. hand,
shield on l. arm. TARL in exergue.
In this case, Mars has a
trophy on l. arm. It's still unlisted but it should come after RIC VII Arles 26.
By the way, i have a doubt: RIC 25 has a H6 left bust type but there aren't other coins with such bust type from Arles in RIC VII.
There might be a mistake in the description?
