Typology suggests it is related to the two preceding lots which are attributed as Al.Bg 436. The linking
themes the hammer and the circular item described as a

Al.Bg = Alvarez
Burgos La moneda hispanica desde sus origenes hasta el siglo V. Madrid. 1987.
I know nothing about the
type, but they sure look like tokens to me, associated in some way with either metal working, or the
Roman dated silver mines in the hinterland of
Carthago Nova. Maybe the workers got one of these, which they exchanged for lunch at the canteen?
